Numbers 8:10

Verse Numbers 8:10. Shall put their hands upon the Levites] It has been argued from this that the congregation had a part in the appointment of their own ministers, and that this was done by the imposition of hands. However that may be, it appears that what was done on this occasion meant no more than that the people gave up this whole tribe to God in place of their firstborn; and that by this act they bound themselves to provide for them who, because of their sacred service, could follow no secular work. And surely it was right, that they who served the altar should live by the altar. The ministers of God perform offices for the people which the people cannot perform for themselves; and nothing can be more reasonable than that the people should give them the necessaries and comforts of life while they are thus employed in their behalf.
