You will find lots of interesting laws in the Old Testament of The Holy Bible, about 613 if I am not mistaken. It is confusing because there is uncertainty how many or which of these commandments were directed towards the tribe of Israel, all of humanity, or just men or women.
Whatever the case it, it is like the wild-west of commandments compared to the New Testament. I love it when people quote Old Testament scripture to prove some sort of bigotry they have because in a few moments, I can find an Old Testement commandment that permits the bigot to be put to death (usually by stoning).
We all are violating commandments that are punishable by death every day and most of which have not be retracted or reversed by the new covenant with the blood sacrifice of the ultimate high priest. The point we miss is we are all sinners and we really ought to hate the sin but love the sinner.
Here are some of my personal favorite "OBEY OR DIE -DIVINE DEATH" scriptures:
Leviticus 20:10 -
And the man that committeth adultery with another man's wife, even he that committeth adultery with his neighbour's wife, the adulterer and the adulteress shall surely be put to death.
Leviticus 21:9 -
And the daughter of any priest, if she profane herself by playing the whore, she profaneth her father: she shall be burnt with fire.
Deuteronomy 22: 20-29
A disturbing outline on what to do with various incidents of rape - as complicated as our laws are today. Read to be amazed.
Leviticus 20:15 -
And if a man lie with a beast, he shall surely be put to death: and ye shall slay the beast.
Leviticus 20:17 -
And if a man shall take his sister, his father's daughter, or his mother's daughter, and see her nakedness, and she see his nakedness; it is a wicked thing; and they shall be cut off in the sight of their people: he hath uncovered his sister's nakedness; he shall bear his iniquity.
Exodus 21:15 -

(18)If a man have a stubborn and rebellious son, which will not obey the voice of his father, or the voice of his mother, and that, when they have chastened him, will not hearken unto them:
(19)Then shall his father and his mother lay hold on him, and bring him out unto the elders of his city, and unto the gate of his place;
(20)And they shall say unto the elders of his city, This our son is stubborn and rebellious, he will not obey our voice; he is a glutton, and a drunkard.
(21)And all the men of his city shall stone him with stones, that he die: so shalt thou put evil away from among you; and all Israel shall hear, and fear

Genesis 17:14 -
