Swear now ... - The same request which Jonathan made 1 Samuel 20:15. The deep, genealogical feeling of the Israelites breaks out here as so often elsewhere.

Swear now - Saul knew that an oath would bind David, though it was insufficient to bind himself; see 1 Samuel 19:6. He had sworn to his son Jonathan that David should not be slain; and yet sought by all means in his power to destroy him!

Swear now therefore unto me by the Lord,.... By the Word of the Lord, as the, Targum:

that thou wilt not cut off my seed after me; as was usually done in despotic governments in the eastern countries, and is at this day, when one is advanced to the throne of another, by whom issue is left, who may be rivals and competitors with him:

and that thou wilt not destroy my name out of my father's house; by cutting off his seed, the same thing in different words repeated, for the confirmation of it; children bear the names of their fathers, and by them their memory is perpetuated, and cutting off them is destroying the name of their parents.

Swear now therefore unto me by the LORD, that thou wilt not cut off my seed after me, and that thou wilt not destroy my name out of my father's house.

24:16-22 Saul speaks as quite overcome with David's kindness. Many mourn for their sins, who do not truly repent of them; weep bitterly for them, yet continue in love and in league with them. Now God made good to David that word on which he had caused him to hope, that he would bring forth his righteousness as the light, Ps 37:6. Those who take care to keep a good conscience, may leave it to God to secure them the credit of it. Sooner or later, God will force even those who are of the synagogue of Satan to know and to own those whom he has loved. They parted in peace. Saul went home convinced, but not converted; ashamed of his envy to David, yet retaining in his breast that root of bitterness; vexed that when at last he had found David, he could not find in his heart to destroy him, as he had designed. Malice often seems dead when it is only asleep, and will revive with double force. Yet, whether the Lord bind men's hands, or affect their hearts, so that they do not hurt us, the deliverance is equally from him; it is an evidence of his love, and an earnest of our salvation, and should make us thankful.
