1 Kings 17:13-15

13And 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.

14For 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.'"

15And she went and did as Elijah said. And she and he and her household ate for many days.
