John 5:6 - Coke's Commentary on the Holy Bible

Wilt thou be made whole?— Our Lord proposed this question, that the man might have an opportunity of declaring his case in the hearing of the multitude; (see John 5:13.) because such a declaration tended to make the miracle more conspicuous. It seems he designed to arouse the attention of the inhabitants of the capital; resolving to lay the evidences of his mission before them in the discourse which this miracle was to occasion.
