1. Samuel 13:14

The Lord hath sought him a man after his own heart - That this man was David is sufficiently clear from the sequel. But in what sense was he a man after God's own heart? Answer: 1. In his strict attention to the law and worship of God. 2. In his admitting, in the whole of his conduct, that God was King in Israel, and that he himself was but his vicegerent. 3. In never attempting to alter any of those laws, or in the least change the Israelitish constitution. 4. In all his public official conduct he acted according to the Divine mind, and fulfilled the will of his Maker: thus was he a man after God's own heart. In reference to his private or personal moral conduct, the word is never used. This is the sense alone in which the word is used here and elsewhere; and it is unfair and wicked to put another meaning on it in order to ridicule the revelation of God, as certain infidels have done.

SAUL'S SELECTED BAND. (Sa1 13:1-2) Saul reigned one year--(see Margin). The transactions recorded in the eleventh and twelfth chapters were the principal incidents comprising the first year of Saul's reign; and the events about to be described in this happened in the second year.

But now thy kingdom shall not continue,.... That is, in his family, nor in his tribe, but be removed to another: the Lord hath sought him a man after his own heart: who was David; though as yet Samuel knew him not, he knew by divine revelation that there was another one chosen, to whom the kingdom would be given; a man every way agreeable to the will of God, and who would fulfil his will, though he knew not particularly who he was: and the Lord hath commanded him to be captain over his people; that is, had appointed him to be king over Israel. God's decrees have the force of a law in them, and must be fulfilled; and cannot be resisted so as to be frustrated: because thou hast not kept that which the Lord hath commanded thee; it matters not whether the thing commanded is greater or less, it is disobedience to the command that is the sin, and is resented: this might seem a small thing, since to offer the sacrifice was not criminal; but doing it before the time, a little before it should have been done, not waiting long enough for the prophet; yet it being against the command of God, or in neglect of it, it was sinful, and severely chastised; and the rather, that it might be an example to all succeeding kings how they offended, or broke the least of God's commandments; and this being the first king of Israel, he was made an example of to the rest.

Those that desired a king like all the nations fancied that, when they had one, they should look very great and considerable; but in this chapter we find it proved much otherwise. While Samuel was joined in commission with Saul things went well (Sa1 11:7). But, now that Saul began to reign alone, all went to decay, and Samuel's words began to be fulfilled: "You shall be consumed, both you and your king;" for never was the state of Israel further gone in a consumption than in this chapter. I. Saul appears here a very silly prince. 1. Infatuated in his counsels (Sa1 13:1-3). 2. Invaded by his neighbours (Sa1 13:4, Sa1 13:5). 3. Deserted by his soldiers (Sa1 13:6, Sa1 13:7). 4. Disordered in his own spirit, and sacrificing in confusion (Sa1 13:8-10). 5. Chidden by Samuel (Sa1 13:11-13). 6. Rejected of God from being king (Sa1 13:14). II. The people appear hear a very miserable people. 1. Disheartened and dispersed (Sa1 13:6, Sa1 13:7). 2. Diminished (Sa1 13:15, Sa1 13:16). 3. Plundered (Sa1 13:17, Sa1 13:18). 4. Disarmed (Sa1 13:19-23). This they got by casting off God's government, and making themselves like the nations: all their glory departed from them.

13:14 a man after his own heart: This prophecy pertains to David (see also Acts 13:22) rather than to Saul’s son Jonathan. The rejection of Saul was also the rejection of his family dynasty.
