Sin. Thou hast heard their reproach, O Lord, all their imaginations against me.
Sin. Thou hast heard their reproach, O Lord, all their imaginations against me.
Lamentations 3:59 Res. Thou hast seen, O Lord, their iniquity against me: judge thou my judgment.
Lamentations 3:60 Res. Thou hast seen all their fury, and all their thoughts against me.
Lamentations 3:61 Sin. Thou hast heard their reproach, O Lord, all their imaginations against me.
Lamentations 3:62 Sin. The lips of them that rise up against me: and their devices against me all the day.
Lamentations 3:63 Sin. Behold their sitting down, and their rising up, I am their song.
The verse centers on "thou", "hast", "heard", "reproach", "lord", "imaginations", and "against". It is saying that the verse draws attention to "thou" and "hast", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 60's "Res Thou hast seen all their fury..." into verse 62's "Sin The lips of them that rise...", so "thou" and "hast" 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 "hast" with trust shaped by these words, not by a vague optimism outside the passage.
