2 Samuel 8:2-4

Amplified Bible

² He defeated ^[a]Moab, and ^[b]measured them with a length of rope, making them lie down on the ground; he measured two lengths to [choose those to] put to death, and one full length to [choose those to] be kept alive. And the [surviving] Moabites became servants to David, bringing tribute.

³ Then David defeated Hadadezer the son of Rehob, king of ^[c]Zobah, as he went to restore his power at the River [Euphrates]. ⁴ David captured from him 1,700 horsemen and 20,000 foot soldiers. David also hamstrung all the chariot horses (making them lame), but reserved enough of them for a hundred chariots.
