Every animal killed had to be brought to the tabernacle entrance, to avoid offering it to idols. The blood may not be eaten, but should be covered with earth.
No sex allowed with parents or step-parents, siblings or step-siblings, grandchildren, uncle or aunt, son- or daughter-in-law, the spouse of a sibling, a menstruating woman, anyone else's wife or husband, anyone of the same sex, any animal. Don't take sisters as multiple wives. Don't sacrifice your children to idols. This is the kind of junk I'm kicking the Canaanites out of your land for. Don't copy them!
How this is about Jesus
Jesus rejected the temptation to bow to Satan, worshiping other gods. His blood atones for sin. He was sexually pure.
Sacrificing children to idols during their first year of life was a real practice Molech required. Usually your first child, I think. God's version of this is found in Exodus 13:11-16. The modern equivalent is abortion, to the idol of career, convenience and finance.
Homosexuality is in the same category with incest, abortion and bestiality.
Abortion is closely connected with sexual sin.
"I have given [the blood] for you on the altar to make atonement for your souls, for it is the blood that makes atonement by the life." Leviticus 17:11
