Leviticus 15:1: God's conduct rules?
What does Leviticus 15:1 teach about God's expectations for His people's conduct?

The Lord Initiates and Commands

Leviticus 15:1: “Then the LORD said to Moses and Aaron,”

• God Himself begins the conversation; His expectations are not human inventions but divine revelation.

• The simple phrase “the LORD said” underscores His sovereign right to direct every aspect of His people’s lives (cf. Isaiah 45:12; Psalm 24:1).


Leadership: Moses and Aaron Together

• By addressing both brothers, God binds prophetic (Moses) and priestly (Aaron) authority.

• This dual call signals that truth must be taught (prophet) and applied in worship and daily living (priest).

• It models accountability: leaders hear first, then transmit faithfully (Deuteronomy 6:6-7; Malachi 2:7).


Holiness Reaches the Everyday

• Chapter 15 outlines regulations about bodily discharges—deeply personal matters.

• The placement shows that no area of life is too mundane for God’s concern; holiness embraces the physical as well as the spiritual (Leviticus 11:44-45).

• God’s people are to reflect His purity even in private habits, protecting the camp from defilement and disease (Leviticus 15:31).


Underlying Expectations for Conduct

• Listen: Since God speaks, His people must incline their ears (Psalm 95:7-8).

• Obey: Detailed statutes require careful, wholehearted compliance (Leviticus 18:4-5).

• Teach: Leaders are stewards of revelation; ignorance is no excuse when truth has been clearly delivered (Ezra 7:10).

• Separate from uncleanness: God draws moral and ceremonial lines so His community remains distinct (2 Corinthians 6:17).


Connection to the Wider Canon

• The call to holiness in Leviticus blossoms into the New Covenant expectation: “But just as He who called you is holy, so be holy in all you do” (1 Peter 1:15-16).

• Christ’s atoning work cleanses the deepest impurity, fulfilling the purpose behind these statutes (Hebrews 10:22; Mark 1:40-42).

• Yet the principle endures: God still speaks, still expects obedience, and still uses His Word to shape a distinct, pure people (James 1:22-25).

How can we apply the principles of purity from Leviticus 15:1 today?
