Filling jars of oil

The 4th chapter of 2 Kings starts with a wife of a prophet's son.  She cried out to Elisha that her husband was dead and creditors were coming to take away her two children as slaves in order to pay her debts.

Elisha asked what she had in her house.  She had nothing, except a single jar of oil.

At once, Elisha ordered her to gather up as many empty vessels as she could, even borrowing them from her neighbors.  She filled each vessel until finally all were filled.  That was when there was no more oil.

Elisha then told her to sell all of the oil, and with the money she could pay her debts as well as live comfortably on the rest.
