Matthew groups these two deliverances, that of the two blind men and now that of this mute demon-possessed man; these are Matthew’s own terms. The deliverance of this man amazes the crowd, which is therefore clearly present. Note that he managed to come all the way to the Master.
Matthew evidently seeks to show Jesus’ authority over demonic forces and his ability to heal not only physical illnesses but also spiritual afflictions.
Although Matthew gives no explicit details, we may presume that, as with the blind men, faith plays a crucial role here. This possessed man was unable to express his faith directly, but those who brought him to the Messiah Jesus were convinced that his healing was at hand.
Matthew seems to present not only events, but also a guide for obtaining deliverance God.
Matthew’s remark, “Nothing like this has ever been seen in Israel,” underscores that Jesus’ miracles clearly demonstrated the power of God. Refusing to believe in them became absurd, so evident were these signs. The should likewise have believed.
We see the natural reaction of the crowd, amazed by the events it witnesses. However, the will not share this same reaction.
