'Doorkeeper' in the Bible

Zechariah the son of Meshelemiah was doorkeeper at the entrance to the tent of meeting.

And Kore the son of Jimnah the Levite, the doorkeeper toward the east, was over the voluntary-offerings of God, to distribute the heave-offerings of Jehovah, and the most holy things.

it is as a man gone out of the country, having left his house and given to his bondmen the authority, and to each one his work, and commanded the doorkeeper that he should watch.
