1 Chronicles 9:24-28

The gatekeepers were on the four sides, to the east, west, north, and south.

Their relatives in their settlements were to come in every seven days from time to time to be with them;

for the four chief gatekeepers, who were Levites, served in an official capacity, and were in charge of the chambers and in charge of the treasuries in the house of God.

They spent the night around the house of God, because the watch was committed to them; and they were in charge of opening it morning by morning.

Now some of them were in charge of the utensils of the service, for they counted them when they brought them in and when they took them out.
