21 And, when he had given counsel unto the people, he appointed such as should sing unto Yahweh, and offer praise with holy adorning,as they should be going forth before the armed men, that they should be saying, O give thanks unto Yahweh, For, age-abiding, is his lovingkindness.

22 And, when they began to sing and to praise, Yahweh had set liers-in-wait against the sons of Ammon, Moab and Mount Seir, who were coming against Judah, and they were smitten.
