613 Commandments
The number 613 is often cited as the number of commandments in the Old Testament Law; however, there is no verse in the Bible that gives 613 as the correct enumeration. There are other counts as well. There is no universal agreement among Jews or Christians that there are exactly 613 laws given by God through Moses.
In any calculation of the number of commandments in the Mosaic Law, complications arise. For example, if a command occurs in Exodus and is then repeated in Deuteronomy, does that count as one commandment or two? Further, some commandments can be understood as clarifications of other commandments rather than additional commandments.
