They shall have like portions to eat, {d} beside that which cometh of the sale of his patrimony.

(d) Not forced to live from himself.

Wesley's Notes

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. Beside 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 afterwards he saw occasion for it. Mr. Henry adds a remarkable note here: especially considering he wrote threescore years ago. A hearty, pious zeal to serve God and his church, tho' 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 minster. He shall be as welcome to God as the Levites, whose course it was to minister, and should be so to them.

King James Translators' Notes

that...: Heb. his sale by the fathers

Matthew Henry's Concise Commentary

18:1-8 Care is taken that the priests entangle not themselves with the affairs of this life, nor enrich themselves with the wealth of this world; they have better things to mind. Care is likewise taken that they want not the comforts and conveniences of this life. The people must provide for them. He that has the benefit of solemn religious assemblies, ought to give help for the comfortable support of those that minister in such assemblies.
