But Actually ...
Wrong already. For starters, "You shall not kill" is a mistranslation -- the original Hebrew phrase means "You shall not murder." Legal justification marks a big difference between the two. Which makes a little more sense, since about half the Bible features impaling, mauling, and stabbing people on the toilet.
Giovanni Battista Salvi
"He's just pining."
We generally perceive the commandments to be listed in order of importance, and that makes sense, too: Murder is usually considered a bigger deal than shoplifting, or coveting. But that's not accurate either. In the Bible, the commandments were never listed in a clear manner from one to ten, leading the different religions (and the different subsections within the religions) to interpret the list differently from one another.
In the Protestant version, the first commandment is "You shall have no other gods before me," while the Jewish version interprets that as part of the second commandment. In the Catholic version, "You shall not commit adultery" is the sixth commandment, while in the Protestant version it's the seventh. Oh, also -- "don't murder" isn't number one. On any list. It's not even close.
Thou shalt not lie is the ninth most important rule God could think of.
