Also they were over the bearers of burdens,.... Who carried the timber and stones to the workmen, to look after them, that they were not dilatory, and that the workmen might not stand still for want of materials being brought to them to work with: and were overseers over all that wrought in any manner of service; whether in the way of masonry, or in that of carpenters, or of such that served them, or in whatsoever way: and of the Levites there were scribes, and officers, and porters; some to take the account of the money carried in and paid, who were the scribes, according to Jarchi; and others who looked after the men, and kept them to work, who were the officers; and others that let them in and out, called porters.
