John 18:26

Said one of the high priest's servants, a kinsman of the man whose ear had been cut off by Peter, "Did I not see you with him in the orchard?"

Having said this, Jesus went out with his disciples across the Kidron ravine to an orchard, which he entered in the company of his disciples.

Then Simon Peter, who had a sword, drew it and struck the high priest's servant, cutting off his right ear (the servant's name was Malchus);

After a little the bystanders came up and said to Peter, "To be sure, you are one of them too. Why, your accent betrays you!"

But he denied it again. After a little the bystanders once more said to Peter, "To be sure, you are one of them. Why, you are a Galilean!"

About an hour had passed when another man insisted, "That fellow really was with him. Why, he is a Galilean!"
