In Leviticus Chapter 20, God is concerned about the worship of Molech. Back when this was written, sometime around 1440-1400 BCE, the Yahweh cult was actually in competition with many different gods, one of which was Molech. As we will see, the Old Testament is a record of how the Yahwehists wrested power over the tribe and literally forced the Israelites to follow their god Yahweh, exclusively.

To be fair, Molech isn't exactly a good god to be worshipping. In its most extreme form, worshipping Molech required child sacrifice. Yahweh was a "step up" because he only required animal sacrifice (except for a few instances where there were human sacrifices), and Yahweh's laws were very strict and punishment was usually more than the crime itself.

Molech takes on various forms, a bull (like the Golden Calf), or even an owl (which is a more modern conception). But basically, they're symbols of the same deity.

God then proscribes a few more laws to follow. Yea, He's not very good at transitional material:

1. Kids that curse their parents shall be put to death.
2. Adulterers (and adulteresses) shall be put to death.
3. Men who have sex with their daughter-in-laws - both will be put to death.
4. Men who have sex with men, you too shall die. (Leviticus 20:13)
5. If a man has sex with a woman and her daughter - all of them shall be put to death.
6. Sex with animals - both the human AND the animal must die.
7. If a man sees a female family member's nakedness - he shall be cut off from his people.
8. Worse, if a man sees a female family member's period blood (the Bible calls it 'fountain'), BOTH shall be cut off from the people.
9. Anyone that practices magic should also be put to death.

This sounds familiar, doesn't it? It's because God already covered this in the previous chapters!!!

I skip ahead to Chapter 21, and it's the same. Yahweh repeats His concern about men shaving. And the only new thing is that God also admits that He hates disabled and/or different people, like retarded people, blind, dwarves, people with funny blemishes on their skin, or funny noses, men with damaged testicles, crooked backs, broken hands or feet, and on and on.

Now THAT'S petty!
