Divrey Hayamim Bais 20:24-26

Orthodox Jewish Bible

²⁴ And when Yehudah came toward the mitzpeh (guard tower) in the midbar, they looked toward the multitude, and, hinei, they were pegarim (corpses) fallen on the ground, and there was no escapee.

²⁵ And when Yehoshaphat and his people came to carry off the plunder of them, they found among them in abundance both property with the pegarim, and articles of value, which they stripped off for themselves, more than they could carry away, and they were yamim shelosha in gathering of the plunder, it was so much.

²⁶ And on the fourth day they assembled themselves in the Berachah Valley, for there they blessed Hashem; therefore the shem of that place was called, The Berachah Valley unto this day.
