Charles Ellicott Commentary Judges 20:23

"And the children of Israel went up and wept before Jehovah until even; and they asked of Jehovah, saying, Shall I again draw nigh to battle against the children of Benjamin my brother? And Jehovah said, Go up against him." — Judges 20:23 (ASV)

And the children of Israel. —This verse is parenthetical and retrospective. The whole narrative is arranged in a very simple manner, and shows an unformed archaic style.

Against the children of Benjamin my brother. —The words my brother show a sort of compunction, an uneasy sense that possibly, in spite of the first answer by Urim, God did not approve of a fratricidal war.
