John Calvin Commentary Matthew 9:27

"And as Jesus passed by from thence, two blind men followed him, crying out, and saying, Have mercy on us, thou son of David." — Matthew 9:27 (ASV)

And while Jesus was departing. The other Evangelists say nothing about these two miracles; for, as we have already said, and as John expressly affirms (John 21:25), they did not intend to record every action of Christ, but only to prove, by a brief summary, that he is the Messiah.

Now Matthew relates that sight was restored to two blind men, but not as speedily as Christ was accustomed, on many other occasions, to grant relief to the wretched. While they cry to him on the road, he makes no reply, but, as if he did not appear to notice them, allows them to follow him to his lodging. There he finally asks them what they believed about his power.

Both by action and by words he intended to test their faith; for he holds them in suspense—indeed, he passes by as if he did not hear them—he tries their patience, and what root faith had in their heads. When he afterwards inquires if they believe, he pursues the same investigation. But it may be asked, if a man is convinced of the power of God and of Christ, is that enough to make him a believer? For such appears to be the meaning of the words.
