Passage
Who is he then that sayth, and it commeth to passe, and the Lord commandeth it not?
Who is he then that sayth, and it commeth to passe, and the Lord commandeth it not?
Lamentations 3:35 In ouerthrowing the right of a man before the face of the most high,
Lamentations 3:36 In subuerting a man in his cause: the Lord seeth it not.
Lamentations 3:37 Who is he then that sayth, and it commeth to passe, and the Lord commandeth it not?
Lamentations 3:38 Out of the mouth of the most high proceedeth not euill and good?
Lamentations 3:39 Wherefore then is the liuing man sorowfull? man suffreth for his sinne.
The verse centers on "sayth", "commeth", "passe", "lord", and "commandeth". It is saying that the verse draws attention to "sayth" and "commeth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 36's "In subuerting a man in his cause..." into verse 38's "Out of the mouth of the most...", so "sayth" and "commeth" 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 "sayth" and "commeth" with trust shaped by these words, not by a vague optimism outside the passage.
