1 Kings 17:4-6, 14-16

You shall drink from the brook, and I have commanded the ravens to sustain you there [with food].” So he went and did in accordance with the word of the LORD; he went and lived by the brook Cherith, which is east of the Jordan. And the ravens brought him bread and meat in the morning, and bread and meat in the evening; and he would drink from the brook.

For this is what the LORD God of Israel says: ‘The bowl of flour shall not be exhausted nor shall the jar of oil be empty until the day that the LORD sends rain [again] on the face of the earth.’ ” She went and did as Elijah said. And she and he and her household ate for many days. The bowl of flour was not exhausted nor did the jar of oil become empty, in accordance with the word of the LORD which He spoke through Elijah.
