Charles Ellicott Commentary Judges 21:2

"And the people came to Beth-el, and sat there till even before God, and lifted up their voices, and wept sore." — Judges 21:2 (ASV)

To the house of God. —Rather, to Bethel, as in Judges 20:18; Judges 20:27.

Wept greatly. —As after their defeat (Judges 20:26); but this time they were remorseful for the fate of those whom they were then pledged to destroy.
