Passage
Jehovah is my portion, saith my soul; therefore will I hope in him.
Jehovah is my portion, saith my soul; therefore will I hope in him.
Lamentations 3:22 It is of Jehovah's loving-kindness we are not consumed, because his compassions fail not;
Lamentations 3:23 they are new every morning: great is thy faithfulness.
Lamentations 3:24 Jehovah is my portion, saith my soul; therefore will I hope in him.
Lamentations 3:25 Jehovah is good unto them that wait for him, to the soul [that] seeketh him.
Lamentations 3:26 It is good that one should both wait, and that in silence, for the salvation of Jehovah.
The verse centers on "jehovah", "portion", "saith", "soul", "therefore", and "hope". It is saying that the verse draws attention to "jehovah" and "portion", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 23's "they are new every morning great is..." into verse 25's "Jehovah is good unto them that wait...", so "jehovah" and "portion" 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 "jehovah" and "portion" with trust shaped by these words, not by a vague optimism outside the passage.
