Psalms 137: The songs the captors cannot command

Psalm 137 begins with exiles beside Babylon’s rivers and ends with a violent wish against Babylon’s children. The Book of Psalms does not provide a soft bridge between those points. The captives weep when they remember Zion and hang their harps even though their captors demand music. Their refusal is not a rejection of song itself but a refusal to turn sacred songs of belonging into entertainment for the people who destroyed that belonging. Memory then becomes an oath. The singer binds right hand, tongue, and highest joy to Jerusalem rather than perform forgetfully. In the final section, the same act of remembering is directed toward God: remember Edom, remember what Babylon did, and repay it correspondingly. The last wish reaches the killing of little ones against stones. The psalm neither disguises the victims nor reports divine approval or fulfillment. It preserves the injured community’s desire for retaliation in all its terrible force and stops there.
