Deuteronomy 18:8

Like portions With their brethren, who were in actual ministration: as they share with them in the work, so shall they in the encouragements. Besides that which cometh The reason of this law was, because he that waited on the altar, ought to live by the altar; and because it was fit he should keep his money, wherewith he might redeem what he sold, if afterward he saw occasion for it. Mr. Henry adds a remarkable note here, especially considering he wrote upward of fourscore years ago. “A hearty, pious zeal to serve God and his church, though it may a little encroach upon a settled order, and there may be somewhat in it that looks irregular, yet ought to be gratified, and not discouraged. He that loves dearly to be employed in the service of the sanctuary, in God's name let him minister. He shall be as welcome to God as the Levites, whose course it is to minister, and should be so to them.”
