19:1 And the LORD spoke to Moses, saying, 2 “Speak to all the congregation of the people of Israel and say to them, You shall be holy, for I the LORD your God am holy. 3 Every one of you shall revere his mother and his father, and you shall keep my Sabbaths: I am the LORD your God. 4 Do not turn to idols or make for yourselves any gods of cast metal: I am the LORD your God.

5 “When you offer a sacrifice of peace offerings to the LORD, you shall offer it so that you may be accepted. 6 It shall be eaten the same day you offer it or on the day after, and anything left over until the third day shall be burned up with fire. 7 If it is eaten at all on the third day, it is tainted; it will not be accepted, 8 and everyone who eats it shall bear his iniquity, because he has profaned what is holy to the LORD, and that person shall be cut off from his people.
