In Psalm 137:9, the Jews are singing a song about how they want revenge exacted upon their enemies who treated them cruelty. They are enraged because of their treatment at the hands of the Babylonians.

Subsequently, question is, what are psalms used for? Most individual psalms involve the praise of God—for his power and beneficence, for his creation of the world, and for his past acts of deliverance for Israel. The psalms envision a world in which everyone and everything will praise God, and God in turn will hear their prayers and respond.

Secondly, how does Psalm 137 relate to by the waters of Babylon?

The title By the Waters of Babylon is a clear allusion to Psalm 137 of the Bible, which begins By the Waters of Babylon I sat down and wept. This Psalm is a lament of the Israelites for their lost promised land of Israel from which they have been exiled. Their homeland was destroyed and its people scattered.

How shall we sing the Lords song in a strange land lyrics?
