Mark 7:32-37:

And they bring unto him one that was deaf, and had an impediment in his speech; and they beseech him to put his hand upon him.
And he took him aside from the multitude, and put his fingers into his ears, and he spit, and touched his tongue;
And looking up to heaven, he sighed, and saith unto him, Ephphatha, that is, Be opened.
And straightway his ears were opened, and the string of his tongue was loosed, and he spake plain.
And he charged them that they should tell no man: but the more he charged them, so much the more a great deal they published it;
And were beyond measure astonished, saying, He hath done all things well: he maketh both the deaf to hear, and the dumb to speak.

Notes on Mark 7:32-37:

We cannot surmise from this passage that it is REQUIRED that you put your fingers into the ears of a deaf person, though I’ve seen it done and I have no problem with the practice.  This passage would actually demonstrate that the fingers-in-the-ears action is NOT required, as the people besought Jesus to put His hand on the deaf person – it doesn’t say that the people besought Him to poke His fingers into the deaf person’s ears.
