Then said Jesus unto him,.... With some degree of roughness in his speech, and severity in his countenance, in a way of reproof for his unbelief, as if he could not heal his son without going down to Capernaum along with him:except ye see signs and wonders ye will not believe.
This was the cast of the Jews every where, both in Judea and Galilee; they required signs and miracles to be wrought, in confirmation of Christ's being the Messiah, and which indeed was but right; and Christ did perform them for that purpose: but their sin of unbelief lay in this, that they wanted still more and more signs; they could not be contented with what they had seen, but required more, being sluggish and backward to believe.
