now, behold, I know that you shall surely be king, and that the kingdom of Israel shall be established in your hand.21Swear to me therefore by the Lord that you will not cut off my offspring after me, and that you will not destroy my name out of my father's house.22And David swore this to Saul. Then Saul went home, but David and his men went up to the stronghold.

1And it came to pass, when Saul was returned from following the Philistines, that it was told him, saying, Behold, David is in the wilderness of Engedi.2Then Saul took three thousand chosen men out of all Israel, and went to seek David and his men upon the rocks of the wild goats.3And he came to the sheepcotes by theway, where was a cave; and Saul went in to cover his feet: and David and his men remained in the sides of the cave.4And the men of David said unto him, Behold the day of which the LORD said unto thee, Behold, I will deliver thine enemy into thine hand, that thou mayest do to him as it shall seem good unto thee. Then David arose, and cut off the skirt of Saul's robe privily.5And it came to pass afterward, that David's heart smote him, because he had cut off Saul's skirt.6And he said unto his men, The LORD forbid that I should do this thing unto my master, the LORD's anointed, to stretch forth mine hand against him, seeing he is the anointed of the LORD.7So
