I Kings 17:13

In order, however, to determine with indisputable certainty whether this believing Gentile was the protectress assigned him by the Lord, Elijah comforted her, and at the same time desired her first of all to bake him a little cake משּׁם, i.e., of the last of the meal in the Kad and of the oil in the pitcher, and then to bake for herself and her son, adding this promise: Jehovah the God of Israel will not let the meal in the Kad and the oil in the pitcher fail, till He sends rain upon the earth again. And the widow did according to his word. She gave up the certain for the uncertain, because she trusted the word of the Lord, and received the reward of her believing confidence in the fact that during the whole time of the drought she suffered from no want of either meal or oil. This act of the pious Gentile woman, who had welcomed with a simple heart the knowledge of the true God that had reached her from Israel, must have been the source of strong consolation to Elijah in the hour of conflict, when his faith was trembling because of the multitude of idolaters in Israel. If the Lord Himself had raised up true worshipers of His name among the Gentiles, his work in Israel could not be put to shame. The believing widow, however, received from the prophet not only a material blessing, but a spiritual blessing also. For, as Christ tells His unbelieving contemporaries to their shame (Luk 4:25-26), Elijah was not sent to this widow in order that he might be safely hidden at her house, although this object was better attained thereby than by his remaining longer in Israel; but because of her faith, namely, to strengthen and to increase it, he was sent to her, and not to one of the many widows in Israel, many of whom would also have received the prophet if they had been rescued by…

So sad was the character both of the princes and people of Israel, as described in the foregoing chapter, that one might have expected God would cast off a people that had so cast him off; but, as an evidence to the contrary, never was Israel so blessed with a good prophet as when it was so plagued with a bad king. Never was king so bold to sin as Ahab; never was prophet so bold to reprove and threaten as Elijah, whose story begins in this chapter and is full of wonders. Scarcely any part of the Old Testament history shines brighter than this history of the spirit and power of Elias; he only, of all the prophets, had the honour of Enoch, the first prophet, to be translated, that he should not see death, and the honour of Moses, the great prophet, to attend our Saviour in his transfiguration. Other prophets prophesied and wrote, he prophesied and acted, but wrote nothing; but his actions cast more lustre on his name than their writings did on theirs. In this chapter we have, I. His prediction of a famine in Israel, through the want of rain (Kg1 17:1). II. The provision made for him in that famine, 1. By the ravens at the brook Cherith (Kg1 17:2-7). 2. When that failed, by the widow at Zarephath, who received him in the name of a prophet and had a prophet's reward; for (1.) He multiplied her meal and her oil (Kg1 17:8-16). (2.) He raised her dead son to life (Kg1 17:17-24). Thus his story begins with judgments and miracles, designed to awaken that stupid generation that had to deeply corrupted themselves.

17:13-14 Despite the woman’s dwindling supplies (17:12), Elijah asked her to serve him before herself and her son. Like the poor widow who gave two small coins (Luke 21:1-4), this woman was asked to give all that she had to the Lord’s prophet. True faithfulness means placing God’s Kingdom ahead of personal concerns (Matt 6:33).
