Charles Ellicott Commentary Leviticus 17:3

"What man soever there be of the house of Israel, that killeth an ox, or lamb, or goat, in the camp, or that killeth it without the camp," — Leviticus 17:3 (ASV)

That killeth an ox, or lamb, or goat. —The law so solemnly laid down is that when any of the three kinds of sacrificial quadrupeds are intended for private use, they must not be slaughtered within or outside the camp. That the injunction here refers to the domestic animals in question, and not to the ordinary sacrifices, is not only evident from the expression “killeth,” instead of “sacrificeth,” but more especially from a comparison of Leviticus 17:3-4 with Leviticus 17:8-9.
