Literary Context
Psalm 137 is an exile lament that moves from grief to vow and then to appeal. Earlier lines picture captives in Babylon who cannot sing Zion’s songs and who refuse to forget Jerusalem. Verses 5–6 bind the speaker to remember Jerusalem above personal joy. Verse 7 continues the theme of remembering but shifts the object: now the psalm asks Yahweh to remember Edom’s role in Jerusalem’s collapse. This line sets up the next section’s fierce address against Babylon (vv. 8–9), linking memory of trauma to petitions about how God should respond.
