It is common to ask how many laws are in the Pentateuch. This is a difficult question because of repetition of laws and statements which are nearly the same in different settings. Sometimes one statement is two laws due to differences in application. Sailhamer notes some suggested counts which identify approximately 611-613 laws, the latter number being the total identified by Maimonides in the 12th century AD.
