2 Kings 4:7 (KJV)

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.

Then she came and told the man of God. And he said, Go, sell the oil, and pay thy debt, and live thou and thy children of the rest.

And it fell on a day, that Elisha passed to Shunem, where was a great woman; and she constrained him to eat bread. And so it was, that as oft as he passed by, he turned in thither to eat bread.

And she said unto her husband, Behold now, I perceive that this is an holy man of God, which passeth by us continually.
