Healing of two blind men in the house (peculiar to St. Matthew). Blindness, chiefly as the result of ophthalmia, is exceedingly common in the East, and several miracles of restoring sight to the blind are recorded in the Gospels: Matthew 12:22; Matthew 20:30; Matthew 21:14; John 9. In this case Christ elicited a definite act of faith from the men before healing them. The act of touching their eyes was probably intended to aid their faith. Their addressing Him as Son of David need not imply that they believed Him to be the Messiah.
