Passage
Thou givest to them a covered heart, Thy curse to them.
Thou givest to them a covered heart, Thy curse to them.
Lamentations 3:63 Their sitting down, and their rising up, Behold attentively, I <FI>am<Fi> their song.
Lamentations 3:64 Thou returnest to them the deed, O Jehovah, According to the work of their hands.
Lamentations 3:65 Thou givest to them a covered heart, Thy curse to them.
Lamentations 3:66 Thou pursuest in anger, and destroyest them, From under the heavens of Jehovah!
The verse centers on "thou", "givest", "covered", "heart", and "curse". It is saying that the verse draws attention to "thou" and "givest", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 64's "Thou returnest to them the deed O..." into verse 66's "Thou pursuest in anger and destroyest them...", so "thou" and "givest" 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 "thou" and "givest" with trust shaped by these words, not by a vague optimism outside the passage.
