Leviticus 11:1-13:46

The rules continue. 
Clean and unclean food - they could eat of any animal that had a split hoof AND chewed it's cud.  This eliminated camels, rock badgers, rabbits, pigs. The most prominent one today that people do not eat is pig.  But it is the most widely available of the choices.  Creatures of the sea must have fins and scales.  Wonder if that leaves out crabs, oysters, etc?  (I am so thankful we don't have these restrictions anymore!)  However, we can eat any kind of locust, grasshopper or katydid.  umm... no thanks.  The list goes on and basically if you or anything else touches an unclean animal, then that is unclean as well.  You had to really be vigilant.  Or just know that you have to frequently consecrate yourself.

Purification after Childbirth. The mother is unclean for 7 days and then boy children are circumcised on the 8th.  Then wait another 33 days.  Double all of this for a girl.  THEN she must take a sacrifice to the Tent of Meeting.  It has always been about sacrifice, hasn't it?

Regulations about skin disease, this is where the leper colonies came from "13:45 "The person with such an infectious disease must wear torn clothes, let his hair be unkempt, cover the lower part of his face and cry out, 'Unclean! Unclean!' 46 As long as he has the infection he remains unclean. He must live alone; he must live outside the camp."

Of course over time things were misinterpreted. over-interpreted and basically ignored.  And some of the rules changed with the New Testament.
