2 Samuel 8:1-4

1And after this it came to pass that David smote the Philistines, and subdued them; and David took the power of the capital out of the hand of the Philistines.

2And he smote the Moabites, and measured them with a line, making them lie down on the ground; and he measured two lines to put to death, and one full line to keep alive. And the Moabites became David's servants, [and] brought gifts.

3And David smote Hadadezer, the son of Rehob, king of Zobah, as he went to recover his dominion by the river Euphrates.

4And David took from him one thousand seven hundred horsemen, and twenty thousand footmen; and David houghed all the chariot [horses], but reserved of them [for] a hundred chariots.
