| Clarke's Commentary on the Bible Whatsoever shall touch the flesh thereof shall be holy - The following note of Mr. Ainsworth is not less judicious than it is pious: - "All this rite was peculiar to the sin-offering, (whether it were that which was to be eaten, or that which was to be burnt), above all the other most holy things. As the sin-offering in special sort figured Christ, who was made sin for us, (2 Corinthians 5:21), so this ordinance for all that touched the flesh of the sin-offering to be holy, the garments sprinkled with the blood to be washed, the vessels wherein the flesh was boiled to be broken, or scoured and rinsed - taught a holy use of this mystery of our redemption, whereof they that are made partakers ought to be washed, cleansed, and sanctified by the Spirit of God; that we possess our vessels in holiness and honor, and yield not our members as instruments of unrighteousness unto sin," 1 Thessalonians 4:4; Romans 6:13.
Gill's Exposition of the Entire BibleWhatsoever shall touch the flesh thereof shall be holy,.... None but holy persons, such as were devoted to holy services, even the priests and their sons, might touch and eat of the flesh of the sin offering: all that did so were sacred persons; and even what were used in eating it, dishes and knives, were to be put to no other use, not to any common service, or for anything but holy things; which was done to keep up a veneration for the sacrifices, and especially for the great sacrifice they typified, the sacrifice of Christ, whose flesh is meat indeed; and whoever eats of that by faith dwells in Christ, and Christ dwells in him, John 6:55, and when there is sprinkled of the blood thereof upon any garment; the garment of the priest that slays and offers it: thou shalt wash that whereon it was sprinkled in the holy place; it was not to be carried out of the tabernacle, and washed elsewhere, but in the sanctuary; either at the laver, where the priests washed their hands and feet, or in some room in the court for that purpose. This was done to preserve an esteem and value for the blood of the sacrifice, as typical of the precious blood of Christ.
Geneva Study BibleWhatsoever shall touch the flesh thereof shall be holy: and when there is sprinkled of the blood thereof upon any {k} garment, thou shalt wash that whereon it was sprinkled in the holy place. (k) Meaning, the garment of the priest.
Wesley's Notes 6:27 Upon any garment - Upon the priest's garment; for it was he only that sprinkled it, and in so doing he might easily sprinkle his garments. In the holy place - Partly out of reverence to the blood of sacrifices, which hereby was kept from a profane or common touch; and partly that such garments might be decent, and fit for sacred administrations.
Matthew Henry's Concise Commentary6:24-30 The blood of the sin-offering was to be washed out of the clothes on which it should happen to be sprinkled, which signified the regard we ought to have to the blood of Christ, not counting it a common thing. The vessel in which the flesh of the sin-offering was boiled must be broken, if it were an earthen one; but if a brazen one, well washed. This showed that the defilement was not wholly taken away by the offering; but the blood of Christ thoroughly cleanses from all sin. All these rules set forth the polluting nature of sin, and the removal of guilt from the sinner to the sacrifice. Behold and wonder at Christ's love, in that he was content to be made a sin-offering for us, and so to procure our pardon for continual sins and failings. He that knew no sin was made sin (that is, a sin-offering) for us, 2Co 5:21. Hence we have pardon, and not only pardon, but power also, against sin, Ro 8:3. |
