Leviticus is the third book of the Torah. It gives details of the laws for how the Hebrew people will worship God, what rituals they will follow, and what holy days they will celebrate.Above all, it is concerned with the ways in which something is clean -- and thus allowed to approach the presence of God -- and things which are unclean -- and must be kept away from God's presence. The challenge, though, is that contact with unclean things can make a person unclean, and thus unfit to approach God's presence, so there are many rituals described which allow a person to regain cleanliness or purity.
At times, the long lists of rules and rituals is tedious. However, within these rules are practices that are still followed by many orthodox Jews, and some which influence how Christians worship.
