Although it is at the heart of the Pentateuch, the book of 'Leviticus' is sometimes dismissed as dry and legalistic material with little relevance to modern religions concerns.

But in this commentary Dr. John Hartley perceives that the message of Leviticus - the significance of pure worship and holy living - is also the heart of vital faith in any age.

Amid the prescriptions for sacrifice and ritual to be observed by Israel in the wilderness, the author finds useful observations for the people of God today.

The emphasis of Leviticus on true worship, and on ordering the ethical life according to the will of Yahweh instead of idols, was at the heart of Israel's raison d'etre, Dr. Hartley notes. Viewed in this light, such prescriptions as the 'Holiness Code' (chapters 17-26) are far more than a list of ritual observances; they are Israel's response to God's charge to 'be holy, for I, Yahweh, your God, am holy.'

Leviticus' focus on the Aaronic priesthood also receives special attention in this treatment. The Levites are the designated communicators charged with transmitting God's law through Moses - indeed, the purpose of the book 'to preserve divine sermons for the instruction of the congregation in cultic and ethical matters.' Yet, despite their insistence on correct form and content in worship, the Levites do not become authoritarian protectors of a secret code in the manner of pagan priests. Since the formulas were proclaimed to the congregation, they became an informed laity exerting a balancing dynamic on the priests as well as receiving ministry from them.

The author's sensitivity to theological concern makes this commentary useful in expository preaching. His introduction includes essays on the themes of holiness, God's presence, the covenant, sacrifice, and the relation of Leviticus to the New Testament.
