David divided them into divisions according to the sons of Levi: Gershon, Kohath, and Merari.
      III. The Levites distributed to their respective posts (1 Chronicles 23:4; 1 Chronicles 23:5), that every hand might be employed (for, of all men, an idle Levite makes the worst figure), and that every part of the work might be carefully done. Now it was for the honour of God that so great a number of servants attended his house and the business of it. Much of the state of great men consists in the greatness of their retinue. When God kept house in Israel see what a great household he had, and all well fed and well taught. But what were these to the attendants of his throne above, and the innumerable company of angels? It was the happiness of Israel that they had among them such a considerable body of men who were obliged by their office to promote and keep up religion among them. If the worship of God go to decay in Israel, let it not be said that it was for want of due provision for the support of it, but that those who should have done it were careless and false. The work assigned the Levites was four-fold:-- 1. Some, and indeed far the greater number, were to set forward the work of the house of the Lord: 24,000, almost two-thirds, were appointed for this service, to attend the priests in killing the sacrifices, flaying them, washing them, cutting them up, burning them, to have the meat-offerings and drink-offerings ready, to carry out dirt, and keep all the vessels and utensils of the temple clean, and every thing in its place, that the service might be performed both with expedition and with exactness. These served 1000 a-week, and so went round in twenty-four courses. Perhaps while the temple was in building some of these were employed to set forward that work, to assist the builders, at least to quicken them, and keep good order among them, and the decorum which became temple-work. 2. Others were officers and judges, not in the affairs of the temple, and in the controversies that arose there (for there, we may suppose, the priests presided), but in the country. They were magistrates, to give the laws of God in charge, to resolves difficulties, and to determine controversies that arose upon them. Of these there were 6000, in the several parts of the kingdom, that assisted the princes and elders of every tribe in the administration of justice. 3. Others were porters, to guard all the avenues of the house of God, to examine those that desired entrance, and to resist those that would force an entrance. These were the life-guards of the temple, and probably were armed accordingly. 4. Others were singers and players on instruments, whose business it was to keep up that part of the service; this was a new-erected office.
