2 Chronicles 20:20-26 YLT98

20 And they rise early in the morning, and go out to the wilderness of Tekoa, and in their going out Jehoshaphat hath stood and saith, `Hear me, O Judah, and inhabitants of Jerusalem, remain stedfast in Jehovah your God, and be stedfast;remain stedfast in His prophets, and prosper.'

21 And he taketh counsel with the people, and appointeth singers to Jehovah, and those giving praise to the honour of holiness, in the going out before the armed [men], and saying, `Give ye thanks to Jehovah, for to the age [is] His kindness.'

22 And at the time they have begun with singing and praise, Jehovah hath put ambushments against the sons of Ammon, Moab, and mount Seir, who are coming in to Judah, and they are smitten,

23 and the sons of Ammon stand up, and Moab, against the inhabitants of mount Seir, to devote and to destroy, and at their finishing with the inhabitants of Seir, they helped, a man against his neighbour, to destroy.

24 And Judah hath come in unto the watch-tower, to the wilderness, and they look unto the multitude, and lo, they [are] carcases fallen to the earth, and there is none escaped,

25 and Jehoshaphat cometh in, and his people, to seize their spoil, and they find among them, in abundance, both goods and carcases, and desirable vessels, and they take spoil to themselves without prohibition, and they are three days seizing the spoil, for it [is] abundant.

26 And on the fourth day they have been assembled at the valley of Blessing, for there they blessed Jehovah: therefore they have called the name of that place, `Valley of Blessing,' unto this day.
