'Keeper' in the Bible

Zechariah, the son of Meshelemiah, was keeper of the door of the Tent of meeting.

In the past, when Saul was king, it was you who went at the head of Israel when they went out or came in; and the Lord your God said to you, You are to be the keeper of my people Israel, and their ruler.

And Joab, the son of Zeruiah, was chief of the army; and Jehoshaphat, son of Ahilud, was keeper of the records.
