1 Kings 17:13-16

But Elijah said to her, “Don’t be afraid! Go ahead and do just what you’ve said, but make a little bread for me first. Then use what’s left to prepare a meal for yourself and your son. For this is what the LORD, the God of Israel, says: There will always be flour and olive oil left in your containers until the time when the LORD sends rain and the crops grow again!” So she did as Elijah said, and she and Elijah and her family continued to eat for many days. There was always enough flour and olive oil left in the containers, just as the LORD had promised through Elijah.
