Lev 19:2; Lev 20:2), just as special laws are laid down for the priests in ch. 20 and 21 with reference to the circumstances mentioned there.
verses 3-7
Whoever of the house of Israel slaughtered an ox, sheep, or goat, either within or outside the camp, without bringing the animal to the tabernacle, to offer a sacrifice therefrom to the Lord, “blood was to be reckoned to him;” that is to say, as the following expression, “he hath shed blood,” shows, such slaughtering was to be reckoned as the shedding of blood, or blood-guiltiness, and punished with extermination (see Gen 17:14). The severity of this prohibition required some explanation, and this is given in the reason assigned in Lev 17:5-7, viz., “that the Israelites may bring their slain-offerings, which they slay in the open field, before the door of the tabernacle, as peace-offerings to Jehovah,” and “no more offer their sacrifices to the שׂעירים, after whom they go a whoring” (Lev 17:7). This reason presupposes that the custom of dedicating the slain animals as sacrifices to some deity, to which a portion of them was offered, was then widely spread among the Israelites. It had probably been adopted from the Egyptians; though this is not expressly stated by ancient writers: Herodotus (i. 132) and Strabo (xv. 732) simply mentioning it as a Persian custom, whilst the law book of Manu ascribes it to the Indians. To root out this idolatrous custom from among the Israelites, they were commanded to slay every animal before the tabernacle, as a sacrificial gift to Jehovah, and to bring the slain-offerings, which they would have slain in the open field, to the priest at the tabernacle, as shelamim (praise-offerings and thank-offerings), that he might sprinkle the blood upon the altar, and burn the fat as a sweet-smelling savour for Jehovah (see Lev 3:2-5). “The face of the field” (Lev 17:5, as in Lev 14:7, Lev 14:53): the open field, in distinction from the enclosed space of the court of Jehovah's dwelling. “The altar of Jehovah” is spoken of in Lev 17:6 instead of “the altar” only (Lev 1:5; Lev 11:15, etc.), on account of the contrast drawn between it and the altars upon which they offered sacrifice to Seirim. שׂעירים, literally goats, is here used to signify daemones (Vulg.), “field-devils” (Luther), demons, like the שׂדים in Deu 32:17, who were supposed to inhabit the desert (Isa 13:21; Isa 34:14), and whose pernicious influence they sought to avert by sacrifices.
