The big picture
With Sarah's promised pregnancy approaching, Abraham again calls her his sister. Abimelech takes her into his household, and God intervenes before sexual relations occur. The repetition of chapter 12 exposes persistent fear within a life of faith.
Central truth
Abraham again conceals Sarah's marriage to protect himself, but God restrains Abimelech from sin, requires Sarah's restoration, and brings healing through the prayer of the prophet who caused the danger.

What to explain, in order
Teach the passage in this order. Each step names the verses it rests on, so every point can be shown in the text before it is applied.
Genesis 20:1-2
Start with a repetition that should not happen
Open by reading 20:2 beside 12:11-13. Make the room feel the weight of "She is my sister" spoken again, after God has just promised in 17:19 and 18:10 that Sarah herself will bear the son of promise. Teach this first because the danger in this chapter is not only to Sarah's honour but to the promise: if she is taken into another man's house, whose child will the coming son be. Explain that Gerar lies in the south, between Kadesh and Shur, and that Abraham is still a sojourner, without land or protection of his own.
Genesis 20:3-7
God speaks to the outsider
Now God acts, and he acts through the one person who does not know the truth. Read "thou art but a dead man" (20:3) as a warning given in time, not a sentence carried out. Explain Abimelech's protest about "the integrity of my heart and innocency of my hands" (20:5) and God's agreement with it in 20:6. Then underline the decisive phrase, "I also withheld thee": God is guarding Sarah when her husband will not. Finish the step on 20:7, where Abraham is named a prophet, so the class carries that surprise into the next scene.
Genesis 20:8-13
The rebuke and the excuses
Let Abimelech's questions in 20:9-10 be heard in full. They are the questions a reader wants to ask Abraham. Then read the three parts of the reply slowly: the fear ("Surely the fear of God is not in this place"), the technicality (20:12), and the standing arrangement (20:13). Explain that each part makes the deception worse, not better. This step comes before the restoration because the chapter wants the reader to see the fault plainly before seeing what God does with it. Keep the tone honest rather than mocking; fear is a real human motive.
Genesis 20:14-16
Restoration with a public covering
Abimelech restores Sarah and adds sheep, oxen, servants and freedom to dwell anywhere in his land. Then he gives a thousand pieces of silver and says it is "a covering of the eyes" (20:16). Explain that the phrase most likely means a public vindication: the gift declares to everyone that Sarah has not been wronged. Teach this here because it shows the king making amends for a wrong he did not intend, and it keeps Sarah in view. She is spoken to directly in 20:16, the only person in the chapter whose honour is restored by name.
Genesis 20:17-18
The prayer of the man who caused it
End where the chapter ends: Abraham prays, and God heals Abimelech, his wife and his maidservants, and they bear children. Verse 18 explains backwards that the LORD had closed every womb in the house "because of Sarah Abraham's wife". Draw out two points. First, God's faithfulness to Sarah is the reason for the whole chapter. Second, God uses Abraham's prayer even though Abraham is the cause of the trouble. Then point forward to 21:1-2, where the LORD visits Sarah and she conceives, so the class sees what the protection was for.
Where learners get stuck
The misreadings this passage tends to produce, and how to answer each from the text.
"Abraham did not really lie, because Sarah was his half sister."
Abraham makes that defence himself in 20:12, but the purpose of the words was to make Abimelech believe Sarah was free to marry, and it worked: the king "sent, and took Sarah" (20:2). Abimelech names the result as "a great sin" brought on his kingdom (20:9). The text treats the half truth as a deception, and God's warning in 20:3 calls her "a man's wife". Help learners see that telling part of the truth in order to mislead is still deceit.
"God blessed Abraham's lie, since he came away richer."
The gifts of 20:14-16 come from Abimelech's effort to make amends, not from God's approval of the plan. God's own words in the chapter are a warning to the king and a command to restore Sarah (20:3-7). Abraham is rebuked to his face in 20:9 and has no answer but excuses. What God protects is Sarah and the promise, not Abraham's tactic. Teach that God can bring good out of a situation without endorsing the wrong that caused it.
"People outside God's family have no conscience and cannot know right from wrong."
That was Abraham's assumption in 20:11, and the chapter shows it to be false. Abimelech appeals to integrity (20:5), God agrees with him (20:6), his servants are "sore afraid" at God's warning (20:8), and he rebukes Abraham for "deeds unto me that ought not to be done" (20:9). This does not make Gerar the covenant people, but it does warn believers against assuming the worst of neighbours. Let the class name a time they misjudged someone outside the church.
"If Abimelech was innocent, God was unfair to threaten him and close the wombs."
God speaks the warning before any sin is done, in order to stop it: "thou art but a dead man" is followed by instructions for how to live (20:3, 7). The closing of the wombs (20:18) appears to be part of how God "withheld" the king (20:6), and it is lifted as soon as Sarah is restored and Abraham prays (20:17). Explain that the chapter shows God restraining wrong before it happens, which is mercy to Abimelech as well as protection for Sarah.
Learning objectives
- Compare Abraham's deception here with his earlier Egyptian strategy.
- Distinguish Abimelech's claimed integrity from God's restraining action.
- Identify Sarah's restoration as a required response.
- Explain the contrast between Abraham's assumption and Gerar's response.
- Distinguish a technically true statement from a truthful impression.
- Describe prayer and healing without treating Abraham's conduct as approved.
Teacher preparation
- Read Genesis 12:10–20 and 18:10–14 to place the repeated deception beside the approaching promised birth.
- Explain Abraham and Sarah's stated half-sibling relationship from 20:12 without using it to excuse concealing their marriage.
- Mark the explicit absence of sexual contact in verses 4 and 6; do not imply an alternative father for Isaac.
- Prepare the difficult phrase "covering of the eyes" in verse 16; keep the KJV's conclusion "thus she was reproved" visible.
- Plan a careful discussion of infertility in verses 17–18; do not turn this particular judgment into a general explanation of reproductive illness.
Evidence and interpretation checks
Explicit
Locate Genesis 20:3–7: God identifies Sarah as married, acknowledges Abimelech's integrity, says he restrained him, and orders her return.
Scripture-supported
Pair Genesis 20:13 with 12:13: Abraham describes a continuing concealment strategy that the earlier Egyptian episode already illustrates.
Strong inference
Compare Genesis 20:8–11: Abraham's assumption that the place lacks fear of God is challenged by the king's alarm and moral rebuke.
Possible or traditional reading
Present vindication, compensation, and rebuke as readings discussed around Genesis 20:16's "covering of the eyes"; do not silently replace the KJV wording.
Limit
State that Genesis 20:4–6 excludes sexual contact with Sarah, while 20:17–18 does not establish that infertility generally results from personal wrongdoing.
Discussion with answer guidance
1. How does Abraham's explanation in verse 13 expose a continuing deception about Sarah?
What a good answer contains
In 20:13 Abraham says that when God caused him to wander from his father's house he told Sarah, "This is thy kindness which thou shalt shew unto me; at every place whither we shall come, say of me, He is my brother." So the lie of 12:13 was not a single panic in Egypt; it was a standing arrangement for every place. A good answer links 12:11-19 with 20:2 and notices the cost to Sarah, who is asked to carry the risk twice. A weak answer treats chapter 20 as a fresh mistake.
Show teacher guidance
Compare 12:13–19 with 20:2 and 13. The same protective deception recurs, and Abraham describes an established agreement.
2. What does God affirm and what does God require of Abimelech?
What a good answer contains
God affirms Abimelech's honesty: "Yea, I know that thou didst this in the integrity of thy heart" (20:6). He does not, however, let that settle the matter. The king must act on what he now knows: "restore the man his wife" (20:7), with death as the stated consequence of refusing. The strong answer keeps both halves, that ignorance spared him guilt for what he had done, and knowledge made him responsible for what he did next.
Show teacher guidance
Read verses 5–7. Integrity about what he knew does not remove the duty to restore Sarah once he is warned.
3. Who prevented Abimelech from touching Sarah?
What a good answer contains
God did. "I also withheld thee from sinning against me: therefore suffered I thee not to touch her" (20:6), and 20:4 confirms that Abimelech "had not come near her". Abimelech's integrity is real but it is not what protected Sarah, and Abraham's plan protected only Abraham. Verse 18 adds that the LORD had closed the wombs of the household, which may be part of how he restrained the king. Answers that credit either man alone have left God out of the verse that names him.
Show teacher guidance
Use verse 6 for God's restraint. Do not attribute the entire outcome either to Abimelech's virtue alone or to Abraham's successful planning.
4. How does the king challenge Abraham's view of Gerar?
What a good answer contains
Abraham excuses himself with "Surely the fear of God is not in this place" (20:11). Yet the king of that place hears God in a dream, rises early, tells his servants, and "the men were sore afraid" (20:8). He then rebukes Abraham with a moral judgement: "thou hast done deeds unto me that ought not to be done" (20:9). A good answer sees the irony the Book of Genesis sets up: the prophet assumed there was no fear of God, and the pagan court shows more of it than he did.
Show teacher guidance
Read verses 8–11. The allegedly godless place hears the warning with fear and identifies deeds that should not be done.
5. Why is "she is my sister" still deceptive?
What a good answer contains
Because a statement can be accurate in its words and false in its purpose. Abraham insists "yet indeed she is my sister; she is the daughter of my father, but not the daughter of my mother; and she became my wife" (20:12). The last clause is the one he left out, and it was the only one that mattered to Abimelech, who took Sarah because he believed her free to marry (20:2-5). A strong answer defines the deception as creating a false impression, not only as uttering a false word.
Show teacher guidance
Place verse 12 beside verses 2–5. The partial truth creates the false impression that Sarah is available for marriage.
6. What is uncomfortable about Abraham praying for the household?
What a good answer contains
God calls Abraham "a prophet" who "shall pray for thee, and thou shalt live" (20:7), and in 20:17 "Abraham prayed unto God: and God healed Abimelech". The man who brought the danger is the one whose prayer removes it. The chapter does not hide the awkwardness: Abraham is rebuked, offers excuses, and receives gifts he did not earn (20:14-16). A good answer lets God's choice of an imperfect intercessor stand without turning it into an excuse for Abraham's conduct.
Show teacher guidance
Read verses 7 and 17–18 beside the deception. His prophetic role remains, but the chapter does not polish away his responsibility.
Responsible application
Heart and habits
Ask learners to evaluate a fictional technically correct statement designed to produce a false belief; compare it with verse 12.
Relationships and community
Draft a fictional leader's response to justified criticism from someone outside the leader's religious community.
Repair before reputation
Trace Sarah's return before the closing healing; ask why restoring the harmed situation matters more than defending a respected person's image.
Session plans
Two timings of the same lesson. The shorter keeps the reading, the central discussion and one response; the longer gives the confusions and the application their own time.
45 minutes
Read it again
Read 12:11-13 and then 20:1-2 aloud. Ask the group what has changed between the two scenes and what has not.
The dream
Read 20:3-7. Take questions two and three and write the words withheld and restore on the board.
Questions from the king
Read 20:8-13. Take question one, then questions four and five together, and use confusion one on the half truth.
Restored and prayed for
Read 20:14-18. Take question six and answer confusion two from the text of the warning in 20:3-7.
Response and handout
Ask each person to write one sentence of the whole truth they need to tell. Read the key verse together and close in prayer.
90 minutes
Opening question
Ask the group whether telling part of the truth is ever honest. Keep the answers visible for later.
The pattern
Read 12:10-20 and 20:1-2. Take question one and map 20:13 onto the earlier scene.
God speaks in the night
Read 20:3-7. Take questions two and three, and confusion four on whether God was unfair to the king.
The rebuke
Read 20:8-13 with one reader for Abimelech and one for Abraham. Take questions four and five and confusion three.
Making amends
Read 20:14-16 and explain the covering of the eyes. Ask who in the chapter is wronged most and how the king addresses her.
The awkward prayer
Read 20:17-18 and 21:1-2. Take question six and confusion two, and return to the opening answers about part truths.
Application
Work through the application on telling the whole relevant truth, in pairs, using a fictional workplace or family case.
Handout and prayer
Read the key verse together, point to the take-home line, and pray for courage to be honest when afraid.
Adapting the lesson
Children
Keep the focus on two simple things: Abraham was afraid and did not tell the whole truth, and God kept Sarah safe anyway. Play a short game where a half true sentence is read out and children say what is missing. Do not explain what a king taking a wife meant. End with God speaking to the king in a dream and Sarah coming home safely.
Youth
Young people know the half truth well, so start with a case: a message that is technically accurate but meant to mislead. Then read 20:12 and ask whether Abraham's defence works. Let them notice the irony of 20:11, that Abraham assumed the worst of people who turned out to fear God more than he did. Keep any talk of marriage simple and respectful of Sarah.
Adults
Adults can trace the pattern from 12:10-20 to 20:13 and ask why fear repeats after promises. Give time to Abimelech as a moral outsider and to God's restraint in 20:6. Discuss how Christians speak about neighbours of other faiths or none. Be careful with spouses in the room: the chapter's victim is Sarah, and no one should leave thinking her safety was a small matter.
One to one
Read the chapter together and ask which character the person most sympathises with. If it is Abraham, talk about fear and the pull to protect ourselves with partial truths. If it is Abimelech, talk about being harmed by someone else's deception. Close on 20:6 and 20:17, where God guards and then heals, and pray about one honest conversation the person needs to have.

The passage in brief
Abraham moves to Gerar and again says that Sarah is his sister, and King Abimelech takes her. God warns the king in a dream and keeps him from touching her, because Sarah is another man's wife. Abimelech confronts Abraham, who admits he was afraid and had planned this from the start. The king restores Sarah with gifts and clears her name. Abraham prays, and God heals the king's household.
A verse to keep
And God said unto him in a dream, Yea, I know that thou didst this in the integrity of thy heart; for I also withheld thee from sinning against me: therefore suffered I thee not to touch her.
