'Doorkeeper' in the Bible

The doorkeeper opens it for him, and the sheep hear his voice. He calls his own sheep by name and leads them out.

But Peter remained standing outside by the door. So the other disciple, the one known to the high priest, went out and spoke to the girl who was the doorkeeper and brought Peter in.

Then the slave girl who was the doorkeeper said to Peter, “You aren’t one of this man’s disciples too, are you?”“I am not!” he said.
