1 Chronicles 9:22

In their villages; where their usual residence was, and whence they came to Jerusalem in their courses. Did ordain: in the times of the judges there was much disorder and confusion, both in the Jewish state and church, and the Levites came to the tabernacle promiscuously, and as their inclinations or occasions brought them. But Samuel, the best of judges, having some prospect and good hopes of deliverance from their enemies, and of a happy settlement of the Israelitish church and nation, and observing that the Levites were greatly increased he began to think of establishing some order among the Levites in their ministration about the tabernacle. And these intentions of his probably were communicated by him to David, who after Samuel's death, and his own peaceable settlement in his throne, revived and perfected Samuel's design, and took care to put it in execution. In their set office, Heb. in their faith, or faithfulness, i.e. either,

1. In their office, which is called faithfulness, because this is required in that office. Or,

2. In the faithful discharge of their duty, and in obedience to the will of God, signified to them by revelation, or by the Spirit, as it is said of David, 1 Chronicles 28:12, which they received by faith, and accordingly designed, and David executed it. And so this is added to show that this was no human invention, as some might conceive, but a Divine appointment, to which all ought to submit.
