Mark 7:33

Took him aside (apolabomeno auton). The secrecy here observed was partly to avoid excitement and partly to get the attention of the deaf and dumb demoniac. He could not hear what Jesus said. So Jesus put his fingers into his ears, spat, and touched his tongue. There was, of course, no virtue in the spittle and it is not clear why Jesus used it. Saliva was by some regarded as remedial and was used by exorcists in their incantations. Whether this was a concession to the man's denseness one does not know. But it all showed the poor man that Jesus healed him in his own way.
