When God decided to take the Hebrew people as His own, Moses was called by God to go up Mt Sinai to receive the 10 Commandments. They are the duty owed to God (No false gods; No name in vain, Keep Holy the Sabbath) and duty to self and neighbour (Honour father and mother; Do not murder; Do not commit adultery; Do not steal; Do not bear false witness; Do not covet wife; Do not covet goods.) This was the first step that God called Moses to do as He was setting up a people and their society of 12 tribes in the Holy land. That is the Divine Law. Then there is the Natural Law and Positive Law.
