17:1-9 All the cattle killed by the Israelites, while in the wilderness, were to be presented before the door of the tabernacle, and the flesh to be returned to the offerer, to be eaten as a peace-offering, according to the law. When they entered Canaan, this only continued in respect of sacrifices. The spiritual sacrifices we are now to offer, are not confined to any one place. We have now no temple or altar that sanctifies the gift; nor does the gospel unity rest only in one place, but in one heart, and the unity of the Spirit. Christ is our Altar, and the true Tabernacle; in him God dwells among men. It is in him that our sacrifices are acceptable to God, and in him only. To set up other mediators, or other altars, or other expiatory sacrifices, is, in effect, to set up other gods. And though God will graciously accept our family offerings, we must not therefore neglect attending at the tabernacle.And bringeth it not to the door of the tabernacle of the congregation, to offer it unto the Lord,.... In a public manner, by one of the priests of the Lord; by which it might appear that he did not take upon him to be a priest himself, nor to offer it to an idol:

even that man shall be cut off from his people; from being one of them, and having communion with them, and sharing in their privileges; or by death, either by the hand of the civil magistrate, or rather by the hand of God; so Jarchi, his seed shall be cut off, and his days shall be cut off; that is, he shall die childless, and in the midst of his days, a violent and premature death.
