Leviticus 20

After reading chapter 20:

*This chapter contains the penalties for breaking previously mentioned laws.
-For giving a child to Molech, the penalty is stoning the perpetrator to death and excommunication of the perpetrator's family. Here it seems clearer that this is some kind of child sacrifice, which would be abhorrent.
-For visiting a medium, the penalty is excommunication.
-For cursing a father or mother, death. This is not modern bad language cursing, but old fashioned magical type cursing that is supposed to harm the person cursed, the opposite of blessing. Of course it has no real effect.
-For sleeping with a close female relative, both are to be put to death, no matter if the woman was forced.
-For having intimate relations with another man, both are to be put to death.
-For marrying a woman and her mother, all are to be burnt to death.
-For a man or woman having intimate relations with an animal, both are to be put to death.
-For a man marrying his sister, they will both be excommunicated. This lighter sentence may reflect that this was a more common cultural occurance. Egyptian kings often married their sisters and Abraham did also.
-For sleeping with a menstruating woman, excommunication.
-For sleeping with an aunt or a sister- in- law, they will die childless. That's an odd punishment that doesn't seem to have much punch. What if they don't care? What if they already have children?
-For being a medium, stoning to death, even though mediums are fakes.

One wonders how much stoning, burning, and excommunication actually went on.

The Israelites are to keep all the laws they've been given, including those regarding clean and unclean animals, so that they can possess the land God will give them. All the bad things are what the people who are living in that land have been doing, that's why they deserve to be driven out, according to Yahweh.
