The divisions of the porters - The account of the porters here given makes them only twenty-four in number at any one time; 1 Chronicles 23:5 states that the duty was discharged by 4,000 persons. Perhaps of the 93 chief porters here spoken of 1 Chronicles 26:8-9, 1 Chronicles 26:11, 1 Chronicles 26:24 were always on guard as officers, while of the remaining 3,907, a certain proportion were each day on duty as their subordinates.
