2 Samuel 8:2-4

New Century Version

² He also defeated the people of Moab. He made them lie on the ground, and then he used a rope to measure them. Those who were measured within two rope lengths were killed, but those who were within the next rope length were allowed to live. So the people of Moab became servants of David and gave him the payment he demanded.

³ David also defeated Hadadezer son of Rehob, king of Zobah, as he went to take control again at the Euphrates River. ⁴ David captured one thousand chariots, seven thousand men who rode in chariots, and twenty thousand foot soldiers. He crippled all but a hundred of the chariot horses.
