2 Kings 4:2 (KJV)

Now there cried a certain woman of the wives of the sons of the prophets unto Elisha, saying, Thy servant my husband is dead; and thou knowest that thy servant did fear the Lord: and the creditor is come to take unto him my two sons to be bondmen.

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.
