1 Chronicles 9:26; 1 Chronicles 9:33

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

33 Now these are the singers, heads of fathers' households of the Levites, who lived in the chambers of the temple free from other service; for they were engaged in their work day and night.
