Leviticus 17:3

“What man soever [there be] of the house of Israel, etc.] Whether high or low, rich or poor: that killeth an ox, or lamb, or goat in the camp; which are particularly mentioned, as Gersom observes, because of these the offerings were; for the law respects the killing of them not for common food, but for sacrifice, as appears from the following verses; for this law was to be a statute for ever, whereas in that sense it was not, and could not be observed, especially when they were come into the land of Canaan; nor would it have been decent or convenient to have brought such vast numbers of cattle every day to be killed at the door of the tabernacle, and must have made the service of the priests…”

“Every domesticated animal that was slain for food was a sort of peace-offering Leviticus 17:5. This law could only be kept as long as the children of Israel dwelt in their camp in the wilderness. The restriction was removed before they settled in the holy land, where their numbers and diffusion over the country would have rendered its strict observance impossible. See Deuteronomy 12:15-16, Deuteronomy 12:20-24. Leviticus 17:4 Blood shall be imputed unto that man - i. e. he has incurred guilt in shedding blood in an unlawful manner. Cut off - See Exodus 31:14 note. Leviticus 17:5 Rather, May bring their beasts for slaughter, which they (now) slaughter in the open field. even that they may…”

“That killeth - Not for common use, for such beasts might be killed by any person or in any place but for sacrifice. In the camp, or out of the camp - That is, anywhere. Leviticus 17:4”

“17:3-9 These regulations (see also Deut 12:15-21) indicate that unsupervised sacrifice could easily lead to the integration of pagan elements into the true worship of the Lord (Lev 17:7). Israel was camped around the Tabernacle (Num 2:2-34), so it was not inconvenient to bring an animal to the sanctuary for slaughter. Deuteronomy 12:20-24 anticipates Israel’s settlement in the land and the hardship imposed by this regulation. It permitted slaughtering and eating meat without bringing it to the sanctuary, as long as the blood was not consumed.”

“be of: Lev 17:8, Lev 17:12, Lev 17:13, Lev 17:15 that killeth an: Deu 12:5-7, Deu 12:11-15, Deu 12:20-22, Deu 12:26, Deu 12:27 Leviticus 17:4”

“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…”
