1 Kings 17:8

8-16. the word of the Lord came to him--Zarephath, Sarepta, now Surafend, whither he was directed to go, was far away on the western coast of Palestine, about nine miles south of Sidon, and within the dominions of Jezebel's impious father, where the famine also prevailed. Meeting, at his entrance into the town, the very woman who was appointed by divine providence to support him, his faith was severely tested by learning from her that her supplies were exhausted and that she was preparing her last meal for herself and son. The Spirit of God having prompted him to ask, and her to grant, some necessary succor, she received a prophet's reward (Mt 10:41, 42), and for the one meal afforded to him, God, by a miraculous increase of the little stock, afforded many to her. 1Ki 17:17-24. He Raises Her Son to Life.

Many widows were in Israel in the days of Elias, and some, it is likely, would have bidden him welcome to their houses; yet he is sent to honour and bless with his presence a city of Sidon, a Gentile city, and so becomes the first prophet of the Gentiles. Jezebel was Elijah's greatest enemy; yet, to show her how powerless was her malice, God will find a hiding-place for him even in her own country. The person appointed to entertain Elijah is not one of the rich or great men of Sidon; but a poor widow woman, in want, and desolate, is made both able and willing to sustain him. It is God's way, and it is his glory, to make use of, and put honour upon, the weak and foolish things of the world. O woman, great was thy faith; one has not found the like, no not in Israel. She took the prophet's word, that she should not lose by it. Those who can venture upon the promise of God, will make no difficulty to expose and empty themselves in his service, by giving him his part first. Surely the increase of this widow's faith, so as to enable her thus readily to deny herself, and to depend upon the Divine promise, was as great a miracle in the kingdom of grace, as the increase of her meal and oil in the kingdom of providence. Happy are all who can thus, against hope, believe and obey in hope. One poor meal's meat this poor widow gave the prophet; in recompence of it, she and her son did eat above two years, in a time of famine. To have food from God's special favour, and in such good company as Elijah, made it more than doubly sweet. It is promised to those who trust in God, that they shall not be ashamed in evil time; in days of famine they shall be satisfied.
