2 Samuel 8:1-6

Now after this it came about that David defeated the Philistines and subdued them; and David took control of the chief city from the hand of the Philistines. He defeated Moab, and measured them with the 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 servants to David, bringing tribute. Then David defeated Hadadezer, the son of Rehob king of Zobah, as he went to restore his rule at the River. David captured from him 1,700 horsemen and 20,000 foot soldiers; and David hamstrung the chariot horses, but reserved enough of them for 100 chariots. When the Arameans of Damascus came to help Hadadezer, king of Zobah, David killed 22,000 Arameans. Then David put garrisons among the Arameans of Damascus, and the Arameans became servants to David, bringing tribute. And the LORD helped David wherever he went.
