Charles Ellicott Commentary Lamentations 1:18

"Jehovah is righteous; for I have rebelled against his commandment: Hear, I pray you, all ye peoples, and behold my sorrow: My virgins and my young men are gone into captivity." — Lamentations 1:18 (ASV)

The Lord is righteous ... — An echo from Jeremiah 12:1; 2 Chronicles 12:6. Misery does its work and issues in repentance. The suffering comes from the all-righteous Judge. It is, perhaps, significant that with this beginning of conversion the name “Jehovah” reappears.

All people ... — Better, all peoples. Those addressed are the heathen nations, who are summoned to gaze on the desolate mourners.
