But there came a man of God to him,.... Who the Jews say (f) was the brother of the king, Amos, the father of Isaiah, but without foundation: saying, O king, let not the army of Israel go with thee; to war against Edom; meaning the 100,000 men he had hired, and suggesting that to have them with him would not be to his advantage, but his detriment, for the following reason: for the Lord is not with Israel, to wit: with all the children of Ephraim; they being idolaters, worshippers of the calves; and as they had forsaken the Lord, he had forsaken them; therefore no help could be expected from them; the Targum is,"the Word of the Lord is not their help.'' (f) Seder Olam Rabba, c. 20. Shalshalet Hakabala, fol. 11. 2.
