The version of the Ten Commandments that Alabama Chief Justice Roy Moore has in the courthouse is a highly edited, abridged version that distorts the original version found in the Book of Exodus (there is another version of the Ten Commandments in the Book of Deuteronomy).
One thing to keep in mind is the remarkable fact that the Ten Commandments have no penalties attached to them for disobedience, as self-professed atheist Joseph Lewis points out:
There seems to have been a perfect observance of the rules laid down by Moses, for it does not appear that the Lord visited his vengeance upon any of the people or broke forth upon them. And now the supremely important event is to take place: The Ten Commandments are to be issued!
I quote Chapter 20, verses 1 to 17:
1. And God spake all these words, saying
2. I am the Lord thy God, which have brought thee out of the land of Egypt, out of the house of bondage.
3. Thou shalt have no other gods before me.
4. Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth:
5. Thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me;
6. And shewing mercy unto thousands of them that love me, and keep my commandments.
7. Thou shalt not take the name of the Lord thy God in vain: for the Lord will not hold him guiltless that taketh his name in vain.
8. Remember the sabbath day, to keep it holy.
9. Six days shalt thou labour, and do all thy work:
10. But the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
11. For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it.
12. Honour thy father and thy mother: that thy days may be long upon the land which the Lord thy God giveth thee.
13. Thou shalt not kill.
14. Thou shalt not commit adultery.
15. Thou shall not steal.
16. Thou shalt not bear false witness against thy neighbour.
17. Thou shalt not covet thy neighbour's house, thou shalt not covet thy neighbour's wife, nor his manservant, nor his maidservant, nor his ox, nor his ass, nor any thing that is thy neighbour's.
I count in the above quotation seventeen separate and distinct verses, with at least thirteen separate and distinct "commands." That these seventeen verses and thirteen separate and distinct commands have since been condensed into what are known as the "Ten Commandments" is something that will require analysis, for we shall find that not all the religions which accept these Commandments arranged them alike. Some religious systems fail to include certain provisions that are not in harmony with their ritual, while others number them differently.
