Why avoid leaven in God's offerings?
Why is it important to avoid mixing God's offerings with leavened bread?

The command in Exodus 23:18

“You must not offer the blood of My sacrifices with anything leavened, nor may the fat of My feast remain until morning.” (Exodus 23:18)


Leaven—what it symbolizes

• Throughout Scripture, leaven consistently pictures inward corruption that quietly spreads.

Exodus 12:15 links eating leaven to being “cut off.”

Leviticus 2:11 forbids leaven “as an offering made by fire to the LORD.”

Matthew 16:6-12 shows Jesus equating leaven with false teaching.

1 Corinthians 5:6-8; Galatians 5:9 remind us “a little leaven leavens the whole batch.”

• Unleavened bread therefore represents purity, sincerity, and truth—exactly what God requires in worship.


God’s heart behind the rule

• Protection of holiness—God will not mingle what is holy with what points to sin or decay.

• Purity of worship—He wants His people to recognize sin’s defilement and approach Him with clean hands.

• Daily reminder—each sacrifice without leaven kept Israel mindful that corruption must be removed, not accommodated.


Foreshadowing the perfect sacrifice of Christ

• Passover lamb: Exodus 12 connected unleavened bread with the blood-covered doorposts; together they preview Christ.

• Christ’s sinlessness: “Christ, our Passover Lamb, has been sacrificed” (1 Corinthians 5:7). The absence of leaven pictures His flawless nature.

• Complete separation: Just as no leaven could touch the altar, no sin could be found in Jesus (Hebrews 4:15; 1 Peter 1:19).

• Ongoing feast: “Let us keep the feast… with the unleavened bread of sincerity and truth” (1 Corinthians 5:8). Believers now live out the reality symbolized in the Old Covenant offerings.


Personal application today

• Guard the altar of the heart—refuse compromise that allows sin to mingle with devotion.

• Keep doctrine pure—reject teachings that water down or distort Scripture (2 Timothy 4:3-4).

• Practice sincere worship—approach God through Christ’s finished work, confessing and forsaking known sin (1 John 1:9).

• Celebrate new-creature living—walk in “the unleavened bread of sincerity and truth,” displaying the life of the risen Lord in everyday choices.

How can we ensure our worship aligns with God's standards in Exodus 23:18?
