Psalms 149: The new song and the judgment written

Psalm 149 begins as congregational celebration and ends in judgment. Israel rejoices in its maker and king with a new song, dance, timbrel, and harp, while salvation is described as the adornment of the meek. The joy then extends to the bed and suddenly acquires a weapon: high praise is in the mouth and a two edged sword in the hand. The psalm does not mark that sword as a metaphor or dissolve the following violence into inward struggle. Nations are punished, rulers bound, and a judgment described as written is executed. At the same time, no specific campaign, date, or ruler is identified, so the severe scene should not be pinned to details the text does not supply. The final praise holds received salvation and participation in judgment inside the same difficult conclusion.
