Albert Barnes on Matthew 27:27

Into the common hall. Tho 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.

(1) "common hall" or, "governor's house"
