Res. Thou hast seen all their fury, and all their thoughts against me.
Lamentations 3:58 Res. Thou hast judged, O Lord, the cause of my soul, thou the Redeemer of my life.
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.
The verse centers on "thou", "hast", "seen", "fury", "thoughts", 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 59's "Res Thou hast seen O Lord their..." into verse 61's "Sin Thou hast heard their reproach O...", 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.
