Also of the Nethinims, whom David and the princes had appointed The Gibeonites, who were devoted to the service of the Levites by Joshua and the princes of his time, (Joshua 9:21,) and are said to have been appointed by David and his princes, because they were confirmed by them in their former office, and more particularly applied to the several services of the temple. Of them two hundred and twenty, upon this hasty summons, listed themselves, and had the honour to be expressed by name in Ezra's muster-roll. This success Ezra ascribes to the good hand of God upon them. If, where ministers have been wanting, the vacancies are well supplied, let God have the glory, and his good hand, qualifying them for the service, inclining them to it, and then opening a door of opportunity for them.
