50 And one of them struck the servant of the high priest, cutting off his right ear. 51 But Jesus answered, “No more of this!” And he touched the man’s ear and healed him
Acts 9:4 :
And having fallen on the ground, he heard a voice saying to him, "Saul, Saul, why do you persecute Me?"
Jesus healed the ear of Paul so that later the same Paul could heard the voice of Jesus himself.
