Arise, get thee to Zarephath, which belonged to Zidon, and dwell there: behold, I have commanded a widow woman there to sustain thee.
So he arose and went to Zarephath. And when he came to the gate of the city, behold, the widow woman was there gathering of sticks: and he called to her, and said, Fetch me, I pray thee, a little water in a vessel, that I may drink. 1 Kings 17:9-10

And as she was going to fetch it, he called to her, and said, Bring me, I pray thee, a morsel of bread in thy hand.
And she said, As the Lord thy God liveth, I have not a cake, but an handful of meal in a barrel, and a little oil in a cruse: and, behold, I am getting two sticks, that I may go in and dress it for me and my son, that we may eat it and die. 1 Kings 11-12

And Elijah said unto her, Fear not; go and do as thou hast said: but make me thereof a little cake first, and bring it unto me, and after make for thee and for thy son.
For this saith the Lord God of Israel, The barrel of meal shall not waste, neither shall the cruze of oil fail, until the day that the Lord sendeth rain upon the earth.
1 Kings 17:13-14
