O LORD, thou hast seen my wrong: judge thou my cause.
Lamentations 3:57 Thou drewest near in the day that I called upon thee: thou saidst, Fear not.
Lamentations 3:58 O LORD, thou hast pleaded the causes of my soul; thou hast redeemed my life.
Lamentations 3:59 O LORD, thou hast seen my wrong: judge thou my cause.
Lamentations 3:60 Thou hast seen all their vengeance and all their imaginations against me.
Lamentations 3:61 Thou hast heard their reproach, O LORD, and all their imaginations against me;
The verse centers on "lord", "thou", "hast", "seen", "wrong", "judge", and "cause". It is saying that the verse draws attention to "lord" and "thou", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 58's "O LORD thou hast pleaded the causes..." into verse 60's "Thou hast seen all their vengeance and...", so "lord" and "thou" 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 "lord" and "thou" with trust shaped by these words, not by a vague optimism outside the passage.
