2 Chronicles 20:21-23

Young's Literal Translation

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.
