17-24. the son of the woman, the mistress of the house, fell sick—A severe domestic calamity seems to have led her to think that, as God had shut up heaven upon a sinful land in consequence of the prophet, she was suffering on a similar account. Without answering her bitter upbraiding, the prophet takes the child, lays it on his bed, and after a very earnest prayer, had the happiness of seeing its restoration, and along with it, gladness to the widow's heart and home. The prophet was sent to this widow, not merely for his own security, but on account of her faith, to strengthen and promote which he was directed to go to her rather than to many widows in Israel, who would have eagerly received him on the same privileged terms of exception from the grinding famine. The relief of her bodily necessities became the preparatory means of supplying her spiritual wants, and bringing her and her son, through the teachings of the prophet, to a clear knowledge of God, and a firm faith in His word (Lu 4:25).

What have I to do with thee? &c.—Wishing to produce a deep spirit of humility and contrition, Elisha gave a stern repulse to the king of Israel, accompanied by a sarcastic sneer, in bidding him go and consult Baal and his soothsayers. But the distressed condition, especially the imploring language, of the royal suppliants, who acknowledged the hand of the Lord in this distress, drew from the prophet the solemn assurance, that solely out of respect to Jehoshaphat, the Lord's true servant, did he take any interest in Jehoram.

     21, 22. But he sent ambassadors . . . What have I to do with thee, thou king of Judah?—Not wishing to spend time, or strength in vain, Necho informed the king of Judah that he had no intention of molesting the Jews; that his expedition was directed solely against his old Assyrian enemy; and that he had undertaken it by an express commission from God. Commentators are not agreed whether it was really a divine commission given him through Jeremiah, or whether he merely used the name of God as an authority that Josiah would not refuse to obey. As he could not know the truth of Necho's declaration, Josiah did not sin in opposing him; or, if he sinned at all, it was a sin of ignorance. The engagement took place. Josiah was mortally wounded [2Ch 35:23].
