(20) And now, behold, I know well that thou shalt surely be king.--Clericus (in Lange) says: "From this great magnanimity of David, Saul concluded that a man who was much superior in soul to kings could not but reign." This is a good comment, and doubtless expresses something of what was in Saul's mind on this occasion; but more must have been behind to have induced the king to make such a speech to David. Never had he for one moment forgotten his old friend's words--the words of Samuel, whom he too well knew was the prophet of the Most High--when he with all solemnity announced to him, as a message from heaven, that the Lord had rent the kingdom from him, and had given it to a neighbour that was better than he (1Samuel 15:21). Since that awful denunciation, the unhappy Saul was only too sensible that the blessing of Jehovah of Hosts no longer rested on his head, no longer blessed his going out and coming in, while the strange, bright career of the son of Jesse seemed to point him out as the neighbour on whom the choice of God had fallen. Rumours, too, of a mysterious anointing must have long ere this reached Saul; this, joined to the passionate advocacy of Jonathan, and the quiet, steady friendship of Samuel, no doubt convinced King Saul that in the son of Jesse he saw Israel's future monarch. Strong, therefore, in this conviction, and for the time humiliated and grieved at the sorry part he had been playing in this restless persecution of one destined to fill so great a position, the king positively entreats the outlaw to swear to him the strange promise contained in the next (21st) verse.

Verses 20-22. - I know well that thou shalt surely be king. Jonathan had expressed a similar conviction (1 Samuel 23:17), and probably there was a growing popular belief that David was the person in whom Samuel's prophetic words (1 Samuel 15:28) were to be fulfilled. Something may even have been known of the selection of David and his anointing at Bethlehem; not perhaps by the king, but in an indistinct way by the people. As for Saul himself, he must long have felt that God's blessing had departed from him, and, brooding perpetually over Samuel's words, it required but little discernment on his part to make him see that the kingdom which he had forfeited was to be bestowed upon one so worthy of it, and so manifestly protected and blessed by God. He therefore makes David swear that he will not cut off his seed after him (see on 1 Samuel 20:15); and so they part. Saul returns to Gibeah, while David and his men gat them up unto the hold. The word gat up, mounted, suggests that the hold, or fastness, was their previous haunt at Hachilah: They would go down to En-gedi, and the difficulty of obtaining food there for 600 men would be insurmountable, except for a very short period. On the other side of the desert they were in a pastoral country, and the large flock masters there probably from time to time sent them supplies. The position of David was thus improved for the present by Saul s reconciliation with him.

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.And now, behold, I know well that thou shalt surely be king,.... Not merely by the common report, that he was anointed by Samuel, to which yet he might give credit; but by the providence of God prospering and preserving him, and by his princely spirit and behaviour, and by calling to mind what Samuel had said to him, that his kingdom should be given to a neighbour of his better than he, and so David was by his own confession, 1 Samuel 24:17; and the cutting off the skirt of his garment might put him in remembrance of the rending of the skirt of Samuel's mantle, upon which he told Saul his kingdom should be rent from him; though some think that was Saul's skirt, and so now he knew thereby, when David cut off his skirt, that the kingdom would be his; and it is a tradition of the Jews (f), that Samuel said to him at that time, that he that cut off the skirt of his garment should reign after him:

and that the kingdom of Israel shall be established in thine hand; and not be rent from him; and yet notwithstanding after this he sought to destroy him.
