The LORD said to Moses,
"Give the Israelites these instructions, which apply to those who are Israelites by birth as well as to the foreigners living among you. If any among them devote their children as burnt offerings to Molech, they must be stoned to death by people of the community.
I myself will turn against them and cut them off from the community, because they have defiled my sanctuary and profaned my holy name by giving their children to Molech.
And if the people of the community ignore this offering of children to Molech and refuse to execute the guilty parents,
then I myself will turn against them and cut them off from the community, along with all those who commit prostitution by worshiping Molech."
"If any among the people are unfaithful by consulting and following mediums or psychics, I will turn against them and cut them off from the community.
So set yourselves apart to be holy, for I, the LORD, am your God.
Keep all my laws and obey them, for I am the LORD, who makes you holy."
"All who curse their father or mother must be put to death. They are guilty of a capital offense."

If a man has intercourse with both a woman and her mother, such an act is terribly wicked. All three of them must be burned to death to wipe out such wickedness from among you."
"If a man has sexual intercourse with an animal, he must be put to death, and the animal must be killed.
If a woman approaches a male animal to have intercourse with it, she and the animal must both be put to death. Both must die, for they are guilty of a capital offense."
