The strength of Israel - A phrase which occurs only here. The word means, perpetuity, truth, glory, victory, and trust, or confidence.

The Strength of Israel will not lie - What God has purposed he will bring to pass, for he has all power in the heavens and in the earth; and he will not repent - change his purpose - concerning thee.

We may say it was some extenuation of Saul's fault that the people insisted on preserving the best of the prey; for who could resist the demands of a victorious mob? But his crime was in consenting; had he not, the crime would have been theirs alone.

And also the Strength of Israel will not lie nor repent,.... Neither of the evil which he had threatened to Saul in taking away the kingdom from him; nor of the good which he had promised to David in giving it to him; nor of his purpose and promise to Israel to protect and defend them, save and deliver them from the Philistines, and continue them a nation and kingdom: and for the confirmation of all this, this title or character of the Lord is given, "the Strength of Israel"; hence he cannot lie, which is the effect of weakness; nor repent or change his mind, as men do, when something unforeseen arises, which hinders the execution of their first design, and which through weakness they cannot surmount: and hence God would support Israel as a nation, and strengthen them against their enemies, and work deliverance and salvation for them: or "the victory of Israel" (q); the author of Israel's victories, and to whom they are to be ascribed, and who is able to give them more, and would; and as he did especially by David, to whom the kingdom is promised: or "the eternity of Israel" (r); that gives firmness, permanency, and duration to them; all which is true of Israel in a spiritual sense; he gives them spiritual strength, victory over their enemies, sin, Satan, and the world, permanent duration, everlasting salvation, immortality, and eternal life:

for he is not a man, that he should repent; men are weak and feeble, and cannot perform what they purpose or promise, and therefore repent; but God, the Strength of Israel, is able to perform whatever he has purposed or promised, and therefore repents not; men are changeable in their minds, and repent of their first thoughts and designs; but God is unchangeable, and never alters his counsels, breaks his covenant, reverses his blessings, repents of his gifts, nor changes his affections to his Israel. Abarbinel says this may be understood of Saul, and so be given as a reason why God would not repent of the evil he had threatened him with, because he was a man that repented not of his sin; but the first sense is best, and agrees with and is confirmed by Numbers 23:19.

(q) "victoria Israel", Montanus, Vatablus, Piscator; "victor Israelis", Tigurine version. (r) "Aeternitas Israelis", Junius & Tremellius.

And also the {m} Strength of Israel will not lie nor repent: for he is not a man, that he should repent.

(m) Meaning God, who maintains and prefers his own.

15:29 Strength of Israel - So he calls God here, to shew the reason why God neither will nor can lie; because lying proceeds from the sense of a man's weakness, who cannot many times accomplish his design without lying and dissimulation; therefore many princes have used it for this very reason. But God needs no such artifices; he can do whatsoever he pleaseth by his absolute power. Repent - That is, nor change his counsel; which also is an effect of weakness and imperfection, either of wisdom or power. So that this word is not here used in the sense it commonly is when applied to God, as in Jer 11:1 - 23, and elsewhere.

Strength: or, Eternity, or, Victory

29. the Strength of Israel will not lie-Hebrew, "He that gives a victory to Israel," a further rebuke of his pride in rearing the Carmel trophy, and an intimation that no loss would be sustained in Israel by his rejection.

15:24-31 There were several signs of hypocrisy in Saul's repentance. 1. He besought Samuel only, and seemed most anxious to stand right in his opinion, and to gain his favour. 2. He excuses his fault, even when confessing it; that is never the way of a true penitent. 3. All his care was to save his credit, and preserve his interest in the people. Men are fickle and alter their minds, feeble and cannot effect their purposes; something happens they could not foresee, by which their measures are broken; but with God it is not so. The Strength of Israel will not lie.
