Leviticus, Book of

The third book of the Old Testament has been called “the priests’ handbook” because it sets rules for the worship ceremonies as well as for everyday life. It is named for the tribe of Levi, from which all priests of Israel came. The first seven chapters provide rules for offering sacrifices. Other chapters provide rules about what foods to eat, cleanliness, observing the Sabbath, and other actions. Chapter 16 was especially important. It described the Day of Atonement, the day the high priest entered the Most Holy Place in the tabernacle or temple, and gave an offering for his wrongdoings, his family’s, and those of the nation.
