Passage
Thou hast covered Thyself with a cloud, So that prayer doth not pass through.
Thou hast covered Thyself with a cloud, So that prayer doth not pass through.
Lamentations 3:42 We--we have transgressed and rebelled, Thou--Thou hast not forgiven.
Lamentations 3:43 Thou hast covered Thyself with anger, And dost pursue us; Thou hast slain--Thou hast not pitied.
Lamentations 3:44 Thou hast covered Thyself with a cloud, So that prayer doth not pass through.
Lamentations 3:45 Offscouring and refuse Thou dost make us In the midst of the peoples.
Lamentations 3:46 Opened against us their mouth have all our enemies.
The verse centers on "thou", "hast", "covered", "thyself", "cloud", "prayer", "doth", 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 Thyself with anger And..." into verse 45's "Offscouring and refuse Thou dost make us...", 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.
