Leviticus 9:20: Obedience in worship?
What does the offering in Leviticus 9:20 teach about obedience and worship?

The Setting: Israel’s First Public Worship Service

Leviticus 9 records the inaugural day of priestly ministry after the tabernacle’s completion. Moses guides Aaron through each sacrifice exactly as the LORD prescribed in Exodus 29. Nothing is improvised; everything is revealed.


The Verse

“They put the fat portions on the breasts, and Aaron burned the fat on the altar.” (Leviticus 9:20)


Why the Fat and the Breasts?

• Fat portions belonged wholly to God (Leviticus 3:16).

• The breasts were waved before the LORD, then given to the priests (Leviticus 7:30-34).

• By separating them as commanded, Aaron acknowledged God’s exclusive rights and received only what God allowed.


What the Offering Teaches about Obedience

• Exact obedience matters. Aaron burns only the fat, exactly as God said—no shortcuts (Exodus 29:13).

• Obedience precedes blessing. The glory of the LORD appears only after every command is fulfilled (Leviticus 9:23-24).

• Obedience is better than creativity. Israel’s later judgment of Nadab and Abihu (Leviticus 10:1-2) underscores that worship must stay within God’s revealed boundaries (1 Samuel 15:22).

• Obedience affirms God’s holiness. By honoring the “fat portions,” Aaron publicly declares God’s absolute worth.


What the Offering Teaches about Worship

• Worship is God-centered. The choicest portions ascend in smoke to Him alone (Psalm 29:2).

• Worship involves mediation. Aaron, not the people, places the fat on the altar—prefiguring Christ, our High Priest (Hebrews 7:26-27).

• Worship invites divine fire. When obedience and sacrifice align, God responds with visible acceptance (Leviticus 9:24).

• Worship demands separation. Parts reserved for God and parts for priests illustrate that worship sets apart what is holy (2 Corinthians 6:17).

Application Today

• Offer God the best, not the leftovers—time, talents, resources.

• Follow His Word precisely; sincere zeal never excuses disobedience.

• Trust Christ’s priestly mediation; no approach to God succeeds apart from Him (John 14:6).

• Expect God’s presence when worship is ordered by His truth and offered from a devoted heart.
