Do you believe that God wrote the 10 Commandments or was it Moses who wrote them to keep his people in check?

An excellent question. It is interesting to see how religion is used all over the world as a mechanism for keeping the populace "in their place". Particularly in the more extreme dictatorships of the middle East. Whether that was Moses' intention, who knows - a lot of the commandments are more about being a decent human being than being actually proscriptive.
If I covet my neighbours ox (I have no idea where he keeps it right now.) does that really affect the way I live my life?
Honouring ones parents is a good thing though - I must remind my kids.
Stealing and murdering? - I'm guessing that they were probably frowned upon before Moses walked back down the mountain, the same goes for "bearing false witness".

The Old Testament contains many laws/rules enforced by Judaism, that are nothing to do with the 10 commandments. I think they may have more bearing on "people control".

Lets see what the bible says......All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof,
for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work.  (2 Timothy 3:16)

God instructed him what to bring to the people, all the bible was under direct result from what God had told them to write

This is a very shrewd question.
By today's lax standards,the host of rules and petty restrictions in the first five Books (the Pentateuch) of Moses seem overly fascistic and domineering.
However,the Bible does state that Moses received the 10 commandments from God,on Mount Sinai,and he wrote them down.
In a later era, at the Time of Christ,Jesus has said,in the NEW Testament,that people should honour Moses's commandments,and love their neighbours,and love God above all.
So: My reading of it is that Moses never took any credit himself for writing down God's commands to men.He was merely the message-bringer.

A great question and it looks like I have missed the best parts (comments) I believe Moses or someone with great forethought decided to create a set of rules for people to follow and given the backing of God! People would follow them.It certainly helped to keep folk in check.

God Did.. Moses Was A Great
Teacher Of  Them.. Read Exodus 24:12

Hey!
No Mosses did not wrote it . 10 commandments was written by God for his people like you and me. I think you are confused by reading Exodus 34:28. So please read Exodus 24:12 and your doubt will be cleared.
Take care.

No doubt in my mind that it was humans who wrote it.
Same as the Bible... And all of it is behavioral checks.
