Leviticus is the book of holiness. The people whom God created (Genesis) and redeemed (Exodus) are not left to their own devices. They are called to be holy as God is holy. The Hebrew title, And He Called, emphasizes that salvation is not the end of God’s plan and program for believers, but the beginning of God’s plan and program for believers.
Leviticus is from the Latin title for the book, found in the Latin Vulgate. This term comes from the Greek title, found in the Septuagint, Leuitikos meaning “that which pertains to the Levites.” The original Hebrew title Wayyiqra’ means “And He called.”
Christian Bible scholars attribute Moses as the author of Genesis, Exodus, Leviticus, Numbers, and Deuteronomy.
