And they performed the service of their God and the service of purification, as did the singers and the gatekeepers, according to the command of David and his son Solomon.
Thus they were to keep charge of the tent of meeting and the sanctuary, and to attend the sons of Aaron, their brothers, for the service of the house of the Lord.
All these, who were chosen as gatekeepers at the thresholds, were 212. They were enrolled by genealogies in their villages. David and Samuel the seer established them in their office of trust.
