Explanatory Notes on the Whole Bible, by John Wesley, [1754-65], at sacred-texts.com
num 18:1Shall bear the iniquity of the sanctuary - Shall suffer the punishment of all the usurpations, or pollutions of the sanctuary, or the holy things, by the Levites, or any of the people, because you have power from me to keep them all within their bounds. Thus the people are in good measure secured against their fears. Also they are informed that Aaron's high dignity was attended with great burdens, having not only his own, but the people's sins to answer for; and therefore they had no such reason to envy him, if the benefits and dangers were equally considered. The iniquity of your priesthood - That is, Of all the errors committed by yourselves, or by you permitted in others in things, belonging to your priesthood.
num 18:2Unto thee - About sacrifices and offerings and other things, according to the rules I have prescribed them. The Levites are said to minister to Aaron here, to the church, Num 16:9, and to God, Deu 10:8. They shall not contend with thee for superiority, as they have done, but shall be subordinate to thee. Thy sons with thee - Or, both to thee, and to thy sons with thee: Which translation may seem to be favoured by the following words, before the tabernacle, which was the proper place where the Levites ministered. Besides, both the foregoing words, and the two following verses, entirely speak of the ministry of the Levites, and the ministry of the priests is distinctly spoken of, Num 18:5.
num 18:3They charge - That is, that which thou shalt command them and commit unto them.
num 18:5The sanctuary - Of the holy, and of the most holy place.
num 18:6To you they are given as a gift - We are to value it as a great gift of the divine bounty, to have those joined to us, that will be helpful and serviceable to us, in the service of God.
num 18:7The altar - Of burnt - offering. Within the veil - This phrase here comprehends both the holy and the most holy place. As a gift which I have freely conferred upon you, and upon you alone; and therefore let no man henceforth dare either to charge you with arrogance in appropriating this to yourselves, or to invade your office.
num 18:8I have given them - Not only the charge, but the use of them for thyself and family. By reason of the anointing - That is, because thou art priest, and art to devote thyself wholly to my service.
num 18:9Most holy - Such as were to be eaten only by the priests, and that in the sanctuary. Reserved - That is, such sacrifices or parts of sacrifices as were not burnt in the fire. Render unto me - By way of compensation for a trespass committed against me, in which case a ram was to be offered, which was a most holy thing, and may be particularly designed here.
num 18:10In the most holy place - In the court of the priests, where there were places for this use, which is called the most holy place, not simply and absolutely, but in respect of the thing he speaks of because this was the most holy of all the places appointed for eating holy things, whereof some might be eaten in any clean place in the camp, or in their own house.
num 18:13Whatsoever is first ripe - Not only the first - fruits of the oil and wine, and wheat now mentioned, but all other first - fruits of all other grains, and all fruit trees. Clean - And none else, because these were first offered to God, and by consequence given to priests; but for those which were immediately given to the priests, the clean and unclean might eat of them.
num 18:14Devoted - Dedicated to God by vow or otherwise, provided it be such a thing as might be eaten: for the vessels or treasures of gold and silver which were dedicated by Joshua, David, or others, were not the priests, but appropriated to the uses of the temple.
num 18:15Of men - Which were offered to God in his temple, and to his service and disposal.
num 18:16Those that are to be redeemed - Namely, of men only, not of unclean beasts, as is manifest from the time and price of redemption here mentioned, both which agree to men; the time, Num 18:16, the price, Num 3:46-47, but neither agree to unclean beasts, which were to be redeemed with a sheep, Exo 13:13, and that after it was eight days old.
num 18:17Holy - Namely, in a peculiar manner, consecrated to an holy use, even to be sacrificed to God. Deu 15:19.
num 18:18The flesh - All the flesh of them, and not only some parts, as in other sacrifices.
num 18:19A covenant of salt - A durable and perpetual covenant; so called here and Ch2 13:5, either, because salt is a sign of incorruption, as being of singular use to preserve things from corruption: or, because it is ratified on their part by salt, which is therefore called the salt of the covenant, for which the priests were obliged to take care, that it should never be lacking from any meat - offering, Lev 2:13. And this privilege conferred upon the priests is called a covenant because it is given them conditionally, upon condition of their service, and care about the worship of God.
num 18:20In their land - In the land of the children of Israel. You shall not have a distinct portion of land, as the other tribes shall. The reason of this law, was, partly because God would have them wholly devoted to his service, and therefore free from worldly incumbrances; partly, because God had abundantly provided for them otherwise, by tithes and first - fruits and oblations; and partly that by this means being dispersed among the several tribes, they might have the better opportunity for teaching and watching over the people. I am thy part - I have appointed thee a liberal maintenance out of my oblations.
num 18:21The tenth - For the tithes were all given to the Levites, and out of their tithes the tenth was given to the priests.
num 18:22Nigh - So nigh as to do any proper act to the priests or Levites.
num 18:23Their iniquity - The punishment due not only for their own, but also for the people's miscarriage, if it be committed through their connivance or negligence. And this was the reason why the priests withstood King Uzziah, when he would have burnt incense to the Lord.
num 18:24An heave - offering - An acknowledgment that they have all their land and the fruits of it from God's bounty. Note the word heave - offering, which is for the most part understood of a particular kind of offerings heaved or lifted up to the Lord, is here used for any offering.
num 18:26Ye shall offer up an heave - offering - They who are employed in assisting the devotions of others, must be sure to pay their own as an heave - offering. Prayers and praises, or rather the heart lifted up in them, are now our heave - offerings.
num 18:27As though it were the corn - It shall be accepted of you as much as if you offered it out of your own lands and labours.
num 18:28To Aaron - And to his children, who were all to have their share herein.
num 18:29Your gifts - Not only out of your tithes, but out of the other gifts which you receive from the people, and out of those fields which shall belong to your cities. Offer - To the priest. As many gifts, so many heave - offerings; you shall reserve a part out of each of them for the priest. The hallowed part - the tenth part, which was the part or proportion that God hallowed or sanctified to himself as his proper portion.
num 18:31Every place - In every clean place, and not in the holy place only.
num 18:32Neither shall ye pollute the holy things - As you will do, if you abuse their holy offerings, by reserving that entirely to yourselves, which they offer to God to be disposed as he hath appointed, namely, part to you, and part to the priests.
