When we read Scripture, it’s easy to focus on the sweeping narratives—the Israelites leaving Egypt, David facing Goliath, or Elijah calling down fire from heaven. These stories are powerful, but sometimes we overlook the quieter details that God intentionally weaves into His Word.
One of those details is found in the priestly garments—specifically, the colours used in their design. At first glance, these colours may seem decorative. But when we slow down and pay attention, we discover something extraordinary: the colours of the priestly robes contain the story of the Messiah Himself.
Coronation Garments and Sacred Colours
The priestly garments described in Exodus were not ordinary clothing. They were coronation robes, set apart for Aaron and the priests as they were inaugurated into holy service. Scripture tells us these garments were made with blue, purple, and scarlet threads.
Today, let’s focus on the scarlet—the deep crimson red.
That colour came from something known in Scripture as the Crimson Worm.
The Crimson Worm and Royal Dye
In biblical times, the red dye used for priestly garments and the coverings of the tabernacle came from a small creature—the crimson worm. Even today, this dye is still harvested and is often called royal red.
The process was both deliberate and costly. The worm would attach itself to a tree, and its body—while still crimson—would be scraped off to produce this valuable dye. Farms still exist today where these worms are cultivated for this purpose.
But beyond its historical use, the crimson worm carries a deeply spiritual message.
The Life Cycle of the Crimson Worm
The crimson worm’s life cycle is unlike anything else in creation.
When the female worm is ready to lay her eggs—something she does only once in her life—she climbs a tree or fence and attaches herself permanently to the wood. A hard crimson shell forms around her body, so strong that removing it would tear her apart and kill her.
Under this shell, she lays her eggs.
When the larvae hatch, they remain under her body for three days, feeding on her living flesh. At the end of the third day, the mother worm dies. As she does, her body releases a scarlet dye that stains both the wood and her offspring.
On the fourth day, something astonishing happens.
The worm’s body turns into a snow-white, wax-like substance. It flakes off the tree and falls to the ground, looking like wool or snow.
This is not accidental biology. This is intentional design.
A Picture of Jesus on the Cross
Every stage of this worm’s life mirrors the gospel.
The mother worm willingly attaches herself to a tree for the sake of her children. In the same way, Jesus willingly allowed Himself to be nailed to a tree—the cross—for the sake of His children.
“By this we know love, because He laid down His life for us.”
— 1 John 3:16
It wasn’t the nails that kept Jesus on the cross—it was love. He could have called down twelve legions of angels at any moment, but He chose to remain.
This wasn’t an accident. It was always the plan.
“He saved us and called us to a holy life… according to His purpose and grace, given to us in Christ Jesus before the beginning of time.”
— 2 Timothy 1:9
Crushed for Our Redemption
As the larvae feed on the body of the mother, they are marked by her crimson stain for the rest of their lives. They live because she was crushed.
Isaiah prophesied this exact truth centuries before the crucifixion:
“He was pierced for our transgressions, He was crushed for our iniquities… and by His stripes we are healed.”
— Isaiah 53:5
The blood of Christ washes away sin and marks us as His own.
“To Him who loved us and washed us from our sins in His own blood.”
— Revelation 1:5
There is no other way to salvation.
“There is no other name under heaven given to mankind by which we must be saved.”
— Acts 4:12
From Scarlet to White
After her sacrifice, the crimson worm turns white like wool.
Scripture echoes this transformation:
“Though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall be like wool.”
— Isaiah 1:18
The priests wore white linen garments, symbolizing righteousness and purity. Revelation tells us this is also the reward of the faithful:
“Fine linen, bright and pure, was given her to wear—this linen represents the righteous acts of the saints.”
— Revelation 19:8
We are called not only to believe but to take up our cross daily, living as a set-apart people, a royal priesthood.
“I Am a Worm, and Not a Man”
When Jesus cried out on the cross,
“My God, My God, why have You forsaken Me?”
He was quoting Psalm 22—a messianic prophecy written a thousand years before crucifixion even existed.
Hidden within that psalm is a powerful line:
“But I am a worm, and not a man.”
— Psalm 22:6
The Hebrew word used here is “tola”—the crimson worm.
This same word appears in Exodus when describing the scarlet thread used in the priestly garments.
Even in His suffering, Jesus was teaching. Every detail mattered.
God’s Signature in Creation
The crimson worm is not mythology. It is God’s handwriting in creation.
From the priestly robes, to the Psalms, to the cross, to the resurrection—creation itself declares the gospel.
“The heavens declare the glory of God; the skies proclaim the work of His hands.”
— Psalm 19:1
The priests were only a shadow. The robes were only a sign. The worm was only a witness.
But the message is unmistakable:
He was crushed so we could live.
He was stained so we could be made white.
He was sacrificed so we could be perfected.
And once you see it—you can never unsee it.
