Leviticus and Exodus are intrinsically linked, forming a cohesive block that presents God's laws and instructions for the people of Israel.

While Exodus narrates the liberation from Egypt and the covenant at Sinai, Leviticus details how to live in covenant with God, delving into the practical implications of the Law. [1, 2]

Leviticus expands on these foundations, providing detailed instructions on how to live a holy and pleasing life to God:

• Sacrificial system: Leviticus details the different types of sacrifices and their functions in the atonement of sins and communion with God, complementing what was introduced in Exodus. [3-5]
• Priesthood: Exodus describes the selection of Aaron and his sons as priests. Leviticus details the laws and rituals of the priesthood, including the consecration and the crucial role in instructing the people. [6, 7]
• Ritual purity: Leviticus expands the laws of purity and impurity, including dietary restrictions and purification after childbirth, deepening the concept of holiness and separation. [6, 8, 9]

• Moral and social holiness: Leviticus reinforces the moral principles of the Ten Commandments with specific laws on sexuality, interpersonal relationships, and social justice, demonstrating the comprehensiveness of holiness. [10-12]

The connection between the two books is evident in the emphasis on holiness. Exodus presents the holiness of God and the need for the people to separate themselves for Him. Leviticus details how this separation manifests in practical life, through worship, moral conduct, and ritual purity.
Both books contribute to the formation of Israel's identity as a chosen, set-apart, and holy people, called to live in covenant with God.
