31 Then he returned from the region of Tyre, and went through Sidon to the Sea of Galilee, through the region of the Decapolis. 32 And they brought to him a man who was deaf and had an impediment in his speech; and they besought him to lay his hand upon him. 33 And taking him aside from the multitude privately, he put his fingers into his ears, and he spat and touched his tongue; 34 and looking up to heaven, he sighed, and said to him, "Ephphatha," that is, "Be opened." 35 And his ears were opened, his tongue was released, and he spoke plainly. 36 And he charged them to tell no one; but the more he charged them, the more zealously they proclaimed it. 37 And they were astonished beyond measure, saying, "He has done all things well; he even makes the deaf hear and the dumb speak."
Daily Quote from the early church fathers:
The touch of the Lord, by Ephrem the Syrian (306-373 AD)
"That power which may not be handled came down and clothed itself in members that may be touched, that the desperate may draw near to him, that in touching his humanity they may discern his divinity. For that speechless man the Lord healed with the fingers of his body. He put his fingers into the man's ears and touched his tongue. At that moment with fingers that may be touched, he touched the Godhead that may not be touched. Immediately this loosed the string of his tongue (Mark 7:32-37), and opened the clogged doors of his ears. For the very architect of the body itself and artificer of all flesh had come personally to him, and with his gentle voice tenderly opened up his obstructed ears. Then his mouth which had been so closed up that it could not give birth to a word, gave birth to praise him who made its barrenness fruitful. The One who immediately had given to Adam speech without teaching, gave speech to him so that he could speak easily a language that is learned only with difficulty (Genesis 1:27-28).
