John Wesley on 1 Chronicles 9:22

Villages - Where their usual residence was, and whence they came to Jerusalem in their courses. Ordain - In the times of the judges there was much disorder 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 observing they were greatly increased, began to think of establishing order in their ministration. And these intentions of his probably were communicated to David, who after his own peaceable settlement in his throne, revived and perfected Samuel's design, and took care to put it in execution.
