John Gill Commentary 2 Kings 4:5

"So she went from him, and shut the door upon her and upon her sons; they brought [the vessels] to her, and she poured out." — 2 Kings 4:5 (ASV)

So she went from him
And did as he advised her, borrowed many empty vessels of her neighbours, having faith in what the prophet had said to her:

and shut the door upon her, and upon her sons ;
and then went to work as she was directed, with her sons:

who brought the vessels to her ;
the empty ones she had borrowed: and she poured out; the oil out of her pot into them.
