1 Kings 17.8-16
Then the word of the Lord came to him, "Arise, go to Zarephath, which belongs to Sidonia, and dwell there. Behold, I have commanded a widow there to feed you."
So he arose and went to Zarephath; and when he came to the gate of the city, behold, a widow was there gathering sticks; and he called to her, "Bring me a little water in a vessel, that I may drink." And as she was going to bring it, he called to her, and said, "Bring me a morsel of bread in your hand."
And she said, "As your God lives, I have nothing baked, only a handful of wheat in a jar, and a little oil in a cruse; and now, I am gathering a couple of sticks, that I may go in and prepare it for myself and my son, that we may eat it, and die."
And Elijah said to her, "Fear not. Go and do as you have said; but first make me a little cake of it and bring it to me; and afterward make for you and your son.
"For thus says the Lord, the God of Israel, 'The jar of meal shall not be spent, and the cruse of oil shall not fail, until the day 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 meal was not spent, neither did the the cruse of oil fail-- in accord with the word of the Lord which He spoke by Elijah.
