John Gill Commentary 2 Kings 4:2

"And Elisha said unto her, What shall I do for thee? tell me; what hast thou in the house? And she said, Thy handmaid hath not anything in the house, save a pot of oil." — 2 Kings 4:2 (ASV)

And Elisha said to her, what shall I do for you ?
&c.] Or can I do, being poor himself, and unable to relieve her out of his substance, and not knowing where to get anything for her; and so what could she expect from him? signifying, that he pitied her case, but all that he could do was to give her his best advice, and pray for her:

tell me what you have in your house ?
that she could part with and dispose of, in order to pay her debt; and satisfy her creditor:

and she said, your handmaid has nothing in the house, except a
pot of oil ;
that is, nothing of any value; she might have some things, some sort of household goods, though perhaps she had parted with most of them in her poverty; this was the most valuable thing she had.
