Passage
You will give them hardness of heart, your curse to them.
You will give them hardness of heart, your curse to them.
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.
Lamentations 3:66 You will pursue them in anger, and destroy them from under the heavens of Yahweh.
The verse centers on "give", "hardness", "heart", and "curse". It is saying that the verse draws attention to "give" and "hardness", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 64's "You will pay them back Yahweh according..." into verse 66's "You will pursue them in anger and...", so "give" and "hardness" 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 "give" and "hardness" with trust shaped by these words, not by a vague optimism outside the passage.
