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.

The prohibition evidently alludes to the worship of the hirei-footed kind, such as Pan, Faunus, and Saturn, whose recognized symbol was a goat. This was a form of idolatry enthusiastically practised by the Egyptians, particularly in the nome or province of Mendes. Pan was supposed especially to preside over mountainous and desert regions, and it was while they were in the wilderness that the Israelites seem to have been powerfully influenced by a feeling to propitiate this idol. Moreover, the ceremonies observed in this idolatrous worship were extremely licentious and obscene, and the gross impurity of the rites gives great point and significance to the expression of Moses, "they have gone a-whoring."
