Albert Barnes Commentary Matthew 27:27-31

"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. And they platted a crown of thorns and put it upon his head, and a reed in his right hand; and they kneeled down before him, and mocked him, saying, Hail, King of the Jews! And they spat upon him, and took the reed and smote him on the head. And when they had mocked him, they took off from him the robe, and put on him his garments, and led him away to crucify him." — Matthew 27:27-31 (ASV)

Into the common hall. The original word here means, rather, the governor's palace, or dwelling. The trial of Jesus had taken place out of the palace. The Jews would not enter in; and it is probable that courts were held often in a larger and more public place than would be a room in his dwelling. Jesus, being condemned, was led by the soldiers away from the Jews, within this palace, and subjected to their profane mockery and sport.

The whole band. The band or cohort was a tenth part of a Roman legion, and consisted of from four hundred to six hundred men, according to the size of the legion.
