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.
KJV
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.
ASV
