Passage
Give them sorrow of heart, thy curse unto them.
Give them sorrow of heart, thy curse unto them.
Lamentations 3:63 Behold their sitting down, and their rising up; I am their musick.
Lamentations 3:64 Render unto them a recompence, O LORD, according to the work of their hands.
Lamentations 3:65 Give them sorrow of heart, thy curse unto them.
Lamentations 3:66 Persecute and destroy them in anger from under the heavens of the LORD.
The verse centers on "give", "sorrow", "heart", and "curse". It is saying that the verse draws attention to "give" and "sorrow", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 64's "Render unto them a recompence O LORD..." into verse 66's "Persecute and destroy them in anger from...", so "give" and "sorrow" 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 "sorrow" with trust shaped by these words, not by a vague optimism outside the passage.
