There are additional sacrificial and purity laws, especially in Leviticus. The law collections were written in two legal genres: casuistic and apodictic. Casuistic law is case law that is not intended to address every possible legal situation. Instead, a conditional formula is presented and used for drawing conclusions based on association or inference (“If a man rents an ox . . .”). Apodictic law is a direct command or prohibition (“You shall not . . .”).
