'Gatekeeper' in the Bible

Then the sentinel saw another man running, so the sentinel called to the gatekeeper and said, "Look, a man running alone." The king said, "This one also [is] bringing good news."

Zechariah the son of Meshelemiah [was] gatekeeper at the doorway to the tent of assembly.

Now Kore the son of Imlah, the Levite, the gatekeeper of the east gate [was] over the freewill offerings of God, to give offerings to Yahweh and the most holy things.
