(29) All the males among the priests.--Not only did the officiating priest, whose perquisite the flesh of the sin offering became, and his male children, partake of it, but he could invite any other priests and their sons to the meal. It is to this practice that the apostle refers when he says, "We have an altar whereof they have no right to eat which serve the tabernacle" (Hebrews 13:10).

6:24-30 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.And all the males among the priests shall eat thereof,.... As of the meat offerings, Leviticus 6:18 and this shows that not the single priest that offered only ate of it, Leviticus 6:26 but his male children, and not those only, but those of other priests then upon duty, or in the court:

it is most holy; See Gill on Leviticus 6:25.
