Executioner: (Mark 6:27) Instead of the Greek word, Mark here uses a Latin word,
speculator, which literally means "a scout," "a spy," and at length
came to denote one of the armed bodyguard of the emperor. Herod
Antipas, in imitation of the emperor, had in attendance on him a
company of speculatores. They were sometimes employed as
executioners, but this was a mere accident of their office.
