John Gill Commentary 2 Kings 4:30

"And the mother of the child said, As Jehovah liveth, and as thy soul liveth, I will not leave thee. And he arose, and followed her." — 2 Kings 4:30 (ASV)

And the mother of the child said
Having no faith in what the servant was to do, or could do:

as the Lord lives, and as your soul lives, I will not leave you ;
signifying she would not go with his servant, but insisted upon it that he himself go with her, or she would not depart:

and he arose, and followed her ;
influenced by her importunity, and a sense of favours he had received from her, and more especially by the Spirit of God.
