Charles Spurgeon Commentary Matthew 27:27-28

"Then the soldiers of the governor took Jesus into the Praetorium, and gathered unto him the whole band. And they stripped him, and put on him a scarlet robe." — Matthew 27:27-28 (ASV)

Then the soldiers of the governor took Jesus into the common hall, and gathered to him the whole band of soldiers.

And they stripped him, and put on him a scarlet robe.

Some old soldier's coat, which they found lying about, they put on Christ in imitation of the royal robes of Caesar or Herod.
