The Book of Leviticus is the third book of the Jewish Bible and of the Old Testament. Its English name is derived from the Latin Leviticus, taken from Greek word Λευιτικόν, Leuitikon. The book makes specific reference to the Levites, the tribe of Aaron, from whom the Kohanim (priests) descended. The book, however, addresses all the people of Israel (1:2) though some passages address the priests specifically (6:8). 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. The instructions of Leviticus emphasize ritual, legal and moral practices rather than beliefs. The primary aim of this paper is to bring out “the sense of holiness” which Israelites developed by their faithful performance of the sanctuary rituals and strict observance of legal and moral practices as has been instructed by Yahweh; and the secondary aim is to depict how such sense of holiness culminates in the love of God and love of neighbor in human society. The informations in this paper are collected from a number of secondary data.
