1 Chronicles 9:23-27

New International Version

²³ They and their descendants were in charge of guarding the gates of the house of the Lord—the house called the tent of meeting. ²⁴ The gatekeepers were on the four sides: east, west, north and south. ²⁵ Their fellow Levites in their villages had to come from time to time and share their duties for seven-day^(A) periods. ²⁶ But the four principal gatekeepers, who were Levites, were entrusted with the responsibility for the rooms and treasuries^(B) in the house of God. ²⁷ They would spend the night stationed around the house of God,^(C) because they had to guard it; and they had charge of the key^(D) for opening it each morning.
