<P> The Book of Leviticus (/ lɪˈvɪtɪkəs /) is the third book of the Torah and of the Old Testament . Most of its chapters (1--7, 11--27) consist of God's speeches to Moses, in which he is commanded to repeat to the Israelites . This takes place within the story of the Israelites' Exodus after they escaped Egypt and reached Mt . Sinai (Exodus 19: 1). The Book of Exodus narrates how Moses led the Israelites in building the Tabernacle (Exodus 35--40) based on God's instructions (Exodus 25--31). Then in Leviticus, God tells the Israelites and their priests how to make offerings in the Tabernacle and how to conduct themselves while camped around the holy tent sanctuary . Leviticus takes place during the month or month - and - a-half between the completion of the Tabernacle (Exodus 40: 17) and the Israelites' departure from Sinai (Numbers 1: 1, 10: 11). </P> <P> The instructions of Leviticus emphasize ritual, legal and moral practices rather than beliefs . Nevertheless, they reflect the world view of the creation story in Genesis 1 that God wishes to live with humans . The book teaches that faithful performance of the sanctuary rituals can make that possible, so long as the people avoid sin and impurity whenever possible . The rituals, especially the sin and guilt offerings, provide the means to gain forgiveness for sins (Leviticus 4--5) and purification from impurities (Leviticus 11--16) so that God can continue to live in the Tabernacle in the midst of the people . </P> <P> The English name Leviticus comes from the Latin Leviticus, which is in turn from the Greek Greek Λευιτικόν, Leuitikon, referring the priestly tribe of the Israelites, "Levi ." The Greek expression is in turn a variant of the rabbinic Hebrew torat kohanim, "law of priests ." </P> <P> In Hebrew the book is called Vayikra (Hebrew: וַיִּקְרָא ‬), from the first word of the book, Vayikra, "He (God) called ." </P>
