1 Chronicles 9:26

For four strong [men] have the charge of the gates; and the Levites were over the chambers, and they keep watch over the treasures of the house of God.

For these Levites, the four chief porters, were in their set office, and were over the chambers and treasuries of the house of God.

for the four chief gatekeepers, who were Levites, were in an office of trust, and were over the rooms and over the treasuries in God’s house.
