“Jesus answered and said unto them, Go and shew John again those things which ye do hear and see:”
Matthew 11:4 — Greek Interlinear
Church Fathers on Matthew 11:4
The Evangelist had shewn above how by Christ’s miracles and teaching, both His disciples and the multitudes had been instructed; he now shews how this instruction had reached even to John’s disciples, so that they seemed to have some jealousy towards Christ; 'John, when he had heard in his bonds the works of Christ, sent two of his disciples to say unto him, Art thou he that should come, or look we for another?
We must enquire how John, who is a prophet and more than a prophet, who made known the Lord when He came to be baptized, saying, 'Behold the Lamb of God, that taketh away the sine of the world!—why, when he was afterwards cast into prison, he should send his disciples to ask, 'Art thou he that should come, or look we for another?'
19: Some understand it thus; That it was a great thing that John should be so far a prophet, as to acknowledge Christ, and to preach remission of sin; but that like a pious prophet; he could not think that He whom he had believed to be He that should come, was to suffer death; he doubted therefore though not in faith, yet in love. So Peter also doubted, saying, 'This be far from thee, Lord; this shall not be unto thee.' [Matt 16:22]
