sinis,
Any depiction of "God" reflects the culture that produced the depiction. It is their picture of God, but this does not mean that this image of him is true and correct. It is thus more of a description of their culture.
You appear to work on the assumption that the Moses stories are factual accounts, rather than stories created to influence the community that the writers were living in. Some suggest that the Hebrews had always lived in the hills of Canaan, and that they used these stories of Abraham, Moses, Joshua and such with the purpose of saying that they were living in the land that God had given them, with the consequences that this brought. (A study of "Biblical Historiography" would not go astray.)
Our contemporary image of God is largely influenced by the Pauline epistles of the Christian Scriptures (the NT) and by the standards of the community that we live in.
BTW. I suggest to you that the "Ten Commandments" - the words originally written by God - appear at Exodus 34:6-28.
