'Guard' in the Bible

Shallum son of Kore, son of Ebiasaph, son of Korah, and his relatives from his family (the Korahites) were assigned to guard the entrance to the sanctuary. Their ancestors had guarded the entrance to the Lord's dwelling place.

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

They and their descendants were assigned to guard the gates of the Lord's sanctuary (that is, the tabernacle).

The four head gatekeepers, who were Levites, were assigned to guard the storerooms and treasuries in God's sanctuary.

They would spend the night in their posts all around God's sanctuary, for they were assigned to guard it and would open it with the key every morning.

Shuppim and Hosah were assigned the west gate, along with the Shalleketh gate on the upper road. One guard was adjacent to another.
