Again, I'm new here, so forgive me if I post anything that has been discussed ad nauseam. But it is my contention that the Ten Commandments as we know them are not actually the Ten Commandments. When God laid out what we consider to be the Ten Commandments to Moses, he was just talking. Moses wasn't etching anything down onto his iStone. Then when he descended the mountain, he threw the iTablets down in anger and broke them. It never mentions what was actually on those stones or that someone pieced them back together.

Exodus 34:1 says: "And the LORD said unto Moses, Hew thee two tables of stone like unto the first: and I will write upon these tables the words that were in the first tables, which thou brakest."

“I am going to write the same thing on these tablets as I did the first ones. The official tablet commandments are as follows:”

And he goes on to describe a completely different list (Exodus 34:10-26 if you want to read them), omitting the part about not killing for more important commandments, like avoiding yeast, celebrating festivals, and this loosely worded commandment about sacrificing firstborns:

"The first offspring of every womb belongs to me, including all the firstborn males of your livestock, whether from herd or flock.

Redeem the firstborn donkey with a lamb, but if you do not redeem it, break its neck. Redeem all your firstborn sons. No one is to appear before me empty-handed."

Don't get me started on whether or not the Bible endorses human sacrifices... but you would think if God meant livestock, he wouldn't stipulate "including...livestock" and "redeeming" sons in the same manner as donkeys.

Finally, notice that God never says the well-known commandments are actually meant to be commandments. Yet right before he gives us this other list, he says: 34:10 And he said, Behold, I make a covenant:

And when he's done he says:34:27 Then the LORD said to Moses, “Write down all these instructions, for they represent the terms of the covenant I am making with you and with Israel.” So he was there with the LORD forty days and forty nights. He neither ate bread nor drank water. And he wrote on the tablets the words of the covenant, the Ten Commandments.

I make a covenant. Here are the terms of the covenant. Yeast. Sacrifices. Festivals. These are the words of the covenant, THE TEN COMMANDMENTS!

And if you're wondering why God would get rid of the commandments about murder for commandments about yeast and sacrifices, if you've read the Old Testament, you know that murder is committed willy-nilly all the time, whereas improper sacrifice preparation often results in harsh punishment. This is very much in accordance with God's priorities.

I rest my case.
