Psalms 137:1
1By the rivers of Babylon, there we sat down. Yes, we wept, when we remembered Zion.
Clarke: by rivers of captivity the exiles sat and wept at Zion remembered—grief for lost worship and home, not mere nostalgia for comfort.
Tears belong before God. Remembering Zion may still break the heart; honest lament is not unbelief, and grace does not mock the captive’s grief.
Calvin: sitting marks prolonged burial in exile; even Babylon’s pleasant waters could not dry tears while they were cut off from God’s sanctuary on Zion.
Memory of Zion is memory of the LORD’s worship and promise. Affliction that should quicken faith must not be soothed away by pagan luxury.
