1 Kings 17:14-16

The LORD, the God of Israel, says, ‘That jar of flour will never be empty, and the jug will always have oil in it, until the day the LORD sends rain to the land.’ ” So the woman went home and did what Elijah told her to do. And the woman and her son and Elijah had enough food every day. The jar of flour and the jug of oil were never empty, just as the LORD, through Elijah, had promised.
