Boy, for a book that's preceded with "Thou shall not kill," there sure were a lot of offenses that are punishable by death according to said book.
If the Bible Were Law, Would You Qualify for the Death Penalty?
For every one that curseth his father or his mother shall be surely put to death: he hath cursed his father or his mother; his blood shall be upon him. Leviticus 20:9
Working on the Sabbath
Whosoever doeth any work in the Sabbath day, he shall surely be put to death. Exodus 31:15
(Wow, this is hardcore, not that I am complaining about a legitimate reason to not work on Sundays. I work in an accounting firm, many peeps work on Sundays during busy season, does that mean....? :O)
Premarital Sex (girls only)
. . .If, however, this charge is true, that evidence of the young woman's virginity was not found, then they shall bring the young woman out to the entrance of her father's house and the men of her town shall stone her to death, Deuteronomy 22:20
Disobedience (boys only)
If someone has a stubborn and rebellious son who will not obey his father and mother, who does not heed them when they discipline him, then his father and his mother shall take hold of him and bring him out to the elders of his town at the gate of that place. They shall say to the elders of his town, "This son of ours is stubborn and rebellious. He will not obey us. He is a glutton and a drunkard." Then all the men of the town shall stone him to death. Deuteronomy 21:18
Girls who are Raped within the City Limits
If there is a girl who is a virgin engaged to a man, and another man finds her in the city and lies with her, then you shall bring them both out to the gate of that city and you shall stone them to death; the girl, because she did not cry out in the city . . . But if in the field the man finds the girl who is engaged, and the man forces her and lies with her, then only the man who lies with her shall die. Deuteronomy 22:23-25
(Errr... not too sure what to make of the "because she did not cry out in the city" bit, but at least the second half was somewhat more sensible...)
And he that blasphemeth the name of the LORD, he shall surely be put to death, and all the congregation shall certainly stone him: as well the stranger, as he that is born in the land, when he blasphemeth the name of the Lord, shall be put to death. Leviticus 24:16
Anyone Who Tries to Deconvert Yahweh Worshipers
If anyone secretly entices you--even if it is your brother, your father's son or your mother's son, or your own son or daughter, or the wife you embrace, or your most intimate friend--saying, "Let us go worship other gods," . . . you shall surely kill them; your own hand shall be first against them to execute them. Deuteronomy 12:6
(AASFSHNR All: and this is why we should not try to preach atheism. ;)
Men who Lie With Men
If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them. Leviticus 20:13
Men who Lie with Beasts and Beasts who Lie with Men
And if a man lie with a beast, he shall surely be put to death: and ye shall slay the beast. Leviticus 20:15
Gosh, what's with these people and their stonings??
