16 It came to pass, when David had made an end of speaking these words to Saul, that Saul said, “Is this your voice, my son David?” Saul lifted up his voice, and wept. 17 He said to David, “You are more righteous than I; for you have done good to me, whereas I have done evil to you. 18 You have declared this day how you have dealt well with me, because when Yahweh had delivered me up into your hand, you didn’t kill me. 19 For if a man finds his enemy, will he let him go away unharmed? Therefore may Yahweh reward you good for that which you have done to me this day. 20 Now, behold, I know that you shall surely be king, and that the kingdom of Israel shall be established in your hand. 21 Swear now therefore to me by Yahweh, that you will not cut off my seed after me, and that you will not destroy my name out of my father’s house.” 22 David swore to Saul. Saul went home; but David and his men went up to the stronghold.

(Read 1 Samuel 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, Psalm 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.
