Then she came and told the man of God,.... Elisha the prophet, what had been done, what a quantity of oil she had, and advised with him what was to be done with it: and he said, go, sell thy oil, and pay thy debt; what was thus miraculously produced was no doubt very good and excellent, and would fetch a good price; and she is therefore bid to turn it into money, and pay her debts with it; she was not to keep it all for her own use, and indulge to luxury with it, but first pay her just debt, as everyone ought to do that is able: and live thou and thy children of the rest; so that it seems there was enough to pay her debt with it, rid her of her troubles, and somewhat remaining for the support of herself and children.
