There are only the 10-commandements and they appears in both the Old Testament and the New Testaments. Any other law is of man and based and are oddly enough, based on the 10-commanddements. God himself acknowledged that man will be tempted and not follow the 10-commendents thus the reason for a Savior. Notice how He did not enforce these laws to bring man closer to Him. Why then should we?
Actually, there are 613 commandments found in the Old Testament. God gave 613 commandments to Moses. There are 3 commandments in Genesis, 111 in Exodus, 247 in Leviticus, 52 in Numbers and 200 in Deuteronomy. These included 365 prohibitions -- a number equal to the nominal number of days in the year. Also included 248 positive commandments.
