John Gill Commentary John 5:11

"But he answered them, He that made me whole, the same said unto me, Take up thy bed, and walk." — John 5:11 (ASV)

He answered them
That is, the impotent man, who was now made whole, replied to the Jews:

he that made me whole, the same said to me, take up your bed and
walk ;
intimating, that he that had such divine power, as to make him whole, had power to dispense with the sabbath, and such an action on it; and that his word was warrant and authority sufficient, to support him in what he did; for he that had wrought this cure for him, he concluded must be from God; was at least a great prophet, and to be hearkened to and obeyed, in one thing as well as another.
