Passage
Thou hast covered thyself with a cloud, that our prayer should not pass through.
Thou hast covered thyself with a cloud, that our prayer should not pass through.
Lamentations 3:42 We have transgressed and have rebelled: thou hast not pardoned.
Lamentations 3:43 Thou hast covered with anger, and persecuted us: thou hast slain, thou hast not pitied.
Lamentations 3:44 Thou hast covered thyself with a cloud, that our prayer should not pass through.
Lamentations 3:45 Thou hast made us as the offscouring and refuse in the midst of the people.
Lamentations 3:46 All our enemies have opened their mouths against us.
The verse centers on "thou", "hast", "covered", "thyself", "cloud", "prayer", "should", and "pass". 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 43's "Thou hast covered with anger and persecuted..." into verse 45's "Thou hast made us as the offscouring...", 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.
