One of the two who heard John, and followed him, was Andrew, Simon Peter's brother.

One of his disciples, Andrew, Simon Peter's brother, said to him,

That disciple therefore whom Jesus loved said to Peter, "It's the Lord!" So when Simon Peter heard that it was the Lord, he wrapped his coat around him (for he was naked), and threw himself into the sea.

Simon Peter therefore, having a sword, drew it, and struck the high priest's servant, and cut off his right ear. The servant's name was Malchus.

but Peter was standing at the door outside. So the other disciple, who was known to the high priest, went out and spoke to her who kept the door, and brought in Peter.

Then the maid who kept the door said to Peter, "Are you also one of this man's disciples?" He said, "I am not."
