Consider this BiteByte of truth. The distribution of God’s laws expressed in the historical record of the bible reflect a movement from a Theocratic form of Government to a Inner Kingdom based Government.
Heb 8:10 This is the covenant I will establish with the people of Israel after that time, declares the Lord. I will put my laws in their minds and write them on their hearts. I will be their God, and they will be my people.
The Old Testament books of the bible are written under what God considered the Old Covenant i.e. Old Agreement. The agreement was an agreement between God and Man and directly given to the Nation of Israel by God. Those Old Testament laws are expressed in both the BIG TEN that we know as The Ten Commandments and then for the Nation of Israel in very specific laws to used to direct the Nation.
In fact 613 laws that were used to direct the Jewish Nation’s Theocracy probably sounds like a lot laws.
When the Messiah arrives he specifically indicates that he is delivering new commandments and not breaking the Old Testament Laws but fulfilling them.Jesus declares his commandments which are there for the new Kingdom.
