Charles Ellicott Commentary Matthew 27:41

"In like manner also the chief priests mocking [him], with the scribes and elders, said," — Matthew 27:41 (ASV)

The chief priests mocking him, with the scribes and elders — It would seem that all, or nearly all, the members of the Sanhedrin—at least those who had taken part in the condemnation—had come to feast their eyes on their Victim’s sufferings.
