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.
Berean Study Bible (BSB) - 2 Samuel 8:2 >David also defeated the Moabites, made them lie down on the ground, and measured them off with a cord. He measured off with two lengths those to be put to death, and with one length those to be spared. So the Moabites became subject to David and brought him tribute.
