Albert Barnes Commentary Lamentations 3:24

"Jehovah is my portion, saith my soul; therefore will I hope in him." — Lamentations 3:24 (ASV)

The Lord is my portion - “ My portion is Yahweh,” see Numbers 18:20; Psalms 16:5 and following.

Therefore will I hope in him - A more full expression of the confidence present in the prophet’s mind in Lamentations 3:21, but based now upon God’s faithfulness in showing mercy.
