David commanded to gather together the foreigners who were in the land of Israel; and he set masons to hew worked stones to build the house of God.
"David commanded to gather together the sojourners"  (1 Chronicles 22:2). These were the aliens, the original Canaanites, whom Israel enslaved, contrary to God's commandments.  The complete record of this is found in the first chapter of Judges.  (See our Vol. 2, of the Historical Books, Judges and Ruth, pp. 9-22.)   "2 Samuel 20:24 indicates that David used forced labor."[2]
