Judges 20:24-26 Tree of Life Version (TLV)
24 So Bnei-Yisrael advanced against the children of Benjamin on the second day. 25 Benjamin came out against them from Gibeah again the second day and struck down 18,000 of Bnei-Yisrael on the field—all drawing the sword.
26 Then all Bnei-Yisrael went up, and all the people came to Bethel and wept and sat there before Adonai. They fasted that day until evening and they offered burnt-offerings and fellowship offerings before Adonai.
