2 Samuel 1:13-14

The son of a stranger This expression signifies one who resided among the Israelites, and had embraced their religion, though not admitted into their communion. David said, How wast thou not afraid to destroy the Lord's anointed? Who possibly might have recovered, and been carried off by some of his own men; the Philistines, by some extraordinary providence of God, being diverted from the pursuit. It was the greater presumption in this young man to do it, since none of Saul's own servants durst venture upon such an act.
