Passage
For this our heart is faint; for these things our eyes are dim.
For this our heart is faint; for these things our eyes are dim.
Lamentations 5:15 The joy of our heart is ceased; our dance is turned into mourning.
Lamentations 5:16 The crown is fallen from our head: woe unto us, that we have sinned!
Lamentations 5:17 For this our heart is faint; for these things our eyes are dim.
Lamentations 5:18 Because of the mountain of Zion, which is desolate, the foxes walk upon it.
Lamentations 5:19 Thou, O LORD, remainest for ever; thy throne from generation to generation.
The verse centers on "heart", "faint", "things", and "eyes". It is saying that the verse draws attention to "heart" and "faint", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "The crown is fallen from our head..." into verse 18's "Because of the mountain of Zion which...", so "heart" and "faint" 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 "heart" and "faint" with trust shaped by these words, not by a vague optimism outside the passage.
