Leviticus 17:5

They offer — The Israelites, before the building of the tabernacle, did so, from which they are now restrained. Peace — offerings — He nameth not these exclusively from others, as appears from the reason of the law, and from Leviticus 17:8, but because in these the temptation was more common in regard of their frequency, and more powerful, because part of these belonged to the offerer, and the pretence was more plausible, because their sanctity was of a lower degree than others, these being only called holy, and allowed in part to the people, whereas the others are called most holy, and were wholly appropriated either to God, or to the priests.
