Passage
You see their sitting down and their rising up. I am their song.
You see their sitting down and their rising up. I am their song.
Lamentations 3:61 You have heard their reproach, Yahweh, and all their plans against me,
Lamentations 3:62 the lips of those that rose up against me, and their plots against me all day long.
Lamentations 3:63 You see their sitting down and their rising up. I am their song.
Lamentations 3:64 You will pay them back, Yahweh, according to the work of their hands.
Lamentations 3:65 You will give them hardness of heart, your curse to them.
The verse centers on "sitting", "down", "rising", and "song". It is saying that the verse draws attention to "sitting" and "down", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 62's "the lips of those that rose up..." into verse 64's "You will pay them back Yahweh according...", so "sitting" and "down" belong inside that flow. In Lamentations context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "sitting" and "down" with trust shaped by these words, not by a vague optimism outside the passage.
