"So how do you resolve these questions?"
The first time the ten commandments were mentioned is in Exodus 20, not Leviticus, like you said.
Verse 3 of Exodus 20: "You shall have no other Gods before me."
Now in Deuteronomy 6, God gives commands, decrees, and laws, but these are not the ten commandments. These are just other laws. A couple are simmialar to the first commandments, but there are no others.
"Now if this were written by god, the first commandment should be the same in both places. My conclusion, if we presume that there was but one tablet containing the first commandment, is that the bible was written by Rabbis and not god."
Like I said, they are two different commands.
"My only problem with that is that in summarizing the commandments, Jesus referred to the one that starts- Hear O' Israel...".
I assume this quote is what you mean: "Mark 12:28-34
One of the scribes came to Jesus and asked him,
"Which is the first of all the commandments?"
Jesus replied, "The first is this:
Hear, O Israel!
The Lord our God is Lord alone!
You shall love the Lord your God with all your heart,
with all your soul,
with all your mind,
and with all your strength."
Jesus simply used this commandment because it is the most important. God was speaking origanaly to the Hebrews, but not it applies to all. Jesus did not mean 'this is the first commandment in the ten commandments' he meant 'this is the first, MOST IMPORTANT commandment'. This scripture has nothing to do with the ten commandments of Exodus.
Hope that 'resolves your questions'. KC2GWX 73's
