2 Samuel 8:2-4

King James Version

² And he smote Moab, and measured them with a line, casting them down to the ground; even with two lines measured he to put to death, and with one full line to keep alive. And so the Moabites became David's servants, and brought gifts.

³ David smote also Hadadezer, the son of Rehob, king of Zobah, as he went to recover his border at the river Euphrates.

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