2 Kings 4:4 (KJV)

And Elisha said unto her, What shall I do for thee? tell me, what hast thou in the house? And she said, Thine handmaid hath not any thing in the house, save a pot of oil.

Then he said, Go, borrow thee vessels abroad of all thy neighbours, even empty vessels; borrow not a few.

And when thou art come in, thou shalt shut the door upon thee and upon thy sons, and shalt pour out into all those vessels, and thou shalt set aside that which is full.

So she went from him, and shut the door upon her and upon her sons, who brought the vessels to her; and she poured out.

And it came to pass, when the vessels were full, that she said unto her son, Bring me yet a vessel. And he said unto her, There is not a vessel more. And the oil stayed.
