1 Kings 17:13-16

And Elijah said to her, “Do not fear; go and do as you have said. But first make me a little cake of it and bring it to me, and afterward make something for yourself and your son. For thus says the LORD, the God of Israel, ‘The jar of flour shall not be spent, and the jug of oil shall not be empty, until the day that the LORD sends rain upon the earth.’” And she went and did as Elijah said. And she and he and her household ate for many days. The jar of flour was not spent, neither did the jug of oil become empty, according to the word of the LORD that he spoke by Elijah.
