1 Kings 17:4-6, 14-16

Drink from the brook and eat what the ravens bring you, for I have commanded them to bring you food.” So Elijah did as the LORD told him and camped beside Kerith Brook, east of the Jordan. The ravens brought him bread and meat each morning and evening, and he drank from the brook.

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.
