Leviticus 17:1-5

The LORD said to Moses, “Speak to Aaron, his sons, and all the people of Israel. Tell them: ‘This is what the LORD has commanded. If an Israelite kills an ox, a lamb, or a goat either inside the camp or outside it, when he should have brought the animal to the entrance of the Meeting Tent as a gift to the LORD in front of the LORD’s Holy Tent, he is guilty of killing. He has killed, and he must be cut off from the people. This rule is so people will bring their sacrifices, which they have been sacrificing in the open fields, to the LORD. They must bring those animals to the LORD at the entrance of the Meeting Tent; they must bring them to the priest and offer them as fellowship offerings.
