2 Chronicles 20:25-26

25And Jehoshaphat and his people came to plunder the spoil of them, and they found among them in abundance, both riches with the dead bodies, and precious things, and they stripped off for themselves more than they could carry away; and they were three days in plundering the spoil, it was so much.

26And on the fourth day they assembled themselves in the valley of Berachah, for there they blessed Jehovah; therefore the name of that place was called The valley of Berachah, to this day.
