'Doorkeeper' in the Bible

and I brought them into the house of the Lord, into the chamber of the sons of Hanan the son of Igdaliah, the man of God, which was near the chamber of the officials, which was above the chamber of Maaseiah the son of Shallum, the doorkeeper.

It is like a man away on a journey, who upon leaving his house and putting his slaves in charge, assigning to each one his task, also commanded the doorkeeper to stay on the alert.

To him the doorkeeper opens, and the sheep hear his voice, and he calls his own sheep by name and leads them out.

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