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" ; 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" ; 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 Nu 23:19.
