Leviticus 17:1-5

Then the LORD said to Moses, “Give the following instructions to Aaron and his sons and all the people of Israel. This is what the LORD has commanded. “If any native Israelite sacrifices a bull or a lamb or a goat anywhere inside or outside the camp instead of bringing it to the entrance of the Tabernacle to present it as an offering to the LORD, that person will be as guilty as a murderer. Such a person has shed blood and will be cut off from the community. The purpose of this rule is to stop the Israelites from sacrificing animals in the open fields. It will ensure that they bring their sacrifices to the priest at the entrance of the Tabernacle, so he can present them to the LORD as peace offerings.
