When Jesus went back to Lake Galilee, some people brought a deaf-mute man to Jesus and asked him to heal the man, which he did.

Mark 7:31-37

31 Jesus and his disciples left the region around Tyre city and went north through Sidon city, then toward the east through the district of the Ten Towns, and then south to the towns near Lake Galilee. 32 There, people brought to him a man who was deaf and who could hardly talk. They begged Jesus to lay his hands on him in order to heal him. 33 So Jesus took him away from the crowd in order that the two of them could be alone. Then he put one of his fingers into each of the man’s ears. After he spat on his fingers, he touched the man’s tongue with his fingers. 34 Then he looked up toward heaven, he sighed because he was concerned for the man, and then in his own language he said to the man’s ears, “Ephphatha”, which means, “Be opened {Open up}!”. 35 At once the man could hear plainly [MTY]. He also began to speak clearly because what was causing him to be unable to speak was healed {Jesus healed what was causing him to be unable to speak}. 36 Jesus told ◄the people/his friends► not to tell anyone what he had done. But, although he ordered them and others repeatedly not to tell anyone about it, they kept talking about it very much. 37 People who heard about it were utterly amazed and were saying enthusiastically, “Everything he has done is wonderful! Besides doing other amazing things, he enables deaf people to hear! And he enables those who cannot speak to speak!”
