Purification in Old Testament?
How does the concept of purification connect to Old Testament practices?

Setting the Scene in John 11:55

“Now the Jewish Passover was near, and many people went up from the country to Jerusalem to purify themselves before the Passover.” (John 11:55)

• Crowds stream toward Jerusalem, eager to celebrate Passover.

• Before they can share the sacrificial meal, they want to be ceremonially clean.

• Their journey reflects centuries-old commands that linked worship with purification.


Purification in the Law of Moses

God wove cleansing rituals into Israel’s daily life:

Exodus 19:10 – Before Sinai, “Go to the people and consecrate them today and tomorrow. They must wash their clothes.”

Leviticus 11–15 – Detailed instructions about food, childbirth, skin disease, and bodily discharges all end with washing and waiting.

Numbers 19:17-19 – Water mixed with the ashes of the red heifer is sprinkled “on the third and seventh days” to cleanse those defiled by a corpse.

Deuteronomy 23:10-11 – Even soldiers in camp observe washing after uncleanness.

These commands taught Israel to approach a holy God with clean hands and hearts.


Common Old Testament Scenarios Requiring Purification

• Contact with a dead body (Numbers 19:11-13)

• Skin infections like leprosy (Leviticus 14)

• Emissions or menstrual flow (Leviticus 15)

• Eating or touching unclean animals (Leviticus 11)

• Idolatrous defilement (2 Chronicles 29:15-16)

Each situation ended with washing, waiting until evening or seven days, and often offering a sacrifice.


Tools God Provided for Purification

• Running water or immersion in a mikveh (Leviticus 15:13)

• Sacrificial blood applied to altar and worshiper (Leviticus 17:11)

• Hyssop dipped in water or blood for sprinkling (Psalm 51:7; Numbers 19:18)

• The priestly declaration “clean” (Leviticus 13:17)

God’s provision ensured that cleansing was always accessible through obedience.


Spiritual Realities Foreshadowed

• The outward wash pointed to the inward need: “Wash yourselves, cleanse yourselves; remove your evil deeds…” (Isaiah 1:16).

Ezekiel 36:25-26 promises, “I will sprinkle clean water on you, and you will be clean… I will give you a new heart.”

Hebrews 9:13-14 explains that if “the ashes of a heifer” sanctify, “how much more will the blood of Christ… cleanse our consciences.”

The rituals were living parables anticipating Messiah’s ultimate cleansing.


Bringing It Home to John 11:55

• Pilgrims obeyed the Law’s call to purity so they could eat the Passover lamb.

• Ironically, while they purified themselves, leaders plotted to kill the true Lamb of God (John 11:53).

• Their temporary washings contrasted with Jesus’ coming sacrifice, which would offer permanent purification (Hebrews 10:10).

• The scene bridges Old Covenant practice and New Covenant fulfillment on the eve of the cross.


Key Takeaways to Remember

• Purification in the Old Testament centered on readiness to meet God.

• Water, blood, and priestly pronouncement secured external cleanness but pointed beyond themselves.

John 11:55 shows Israel still honoring these commands as Passover approached.

• Jesus, the anticipated Lamb, would soon provide the once-for-all cleansing the Law could only preview.
