(27) An executioner.--St. Mark uses a Latin word, speculator, a word which, originally meaning "watchman" or "sentinel," had come to be applied by Latin writers of the time specifically to soldiers employed, as in this instance, as couriers or messengers (Suet. Caligula, c. 44; Tacit. Hist. xi. 73).
Verse 27. - He sent forth anexecutioner (σπεκουλάτωρα); literally, a soldier of his guard; one of his body-guard, in constant attendance as messenger or executioner. It is a Roman word from speculari, to watch. St. Jerome relates that when the head of the Baptist was brought, Herodias barbarously thrust the tongue through with a bodkin, as Fulvia is said to have done over and over again, the tongue of Cicero; thus verifying what Cicero had once said while living, that "nothing is more revengeful than a woman." Because they could not bear to hear the truth, therefore they bored through with a bodkin the tongue that had spoken the truth.
6:14-29 Herod feared John while he lived, and feared him still more when he was dead. Herod did many of those things which John in his preaching taught him; but it is not enough to do many things, we must have respect to all the commandments. Herod respected John, till he touched him in his Herodias. Thus many love good preaching, if it keep far away from their beloved sin. But it is better that sinners persecute ministers now for faithfulness, than curse them eternally for unfaithfulness. The ways of God are unsearchable; but we may be sure he never can be at a loss to repay his servants for what they endure or lose for his sake. Death could not come so as to surprise this holy man; and the triumph of the wicked was short.
and commanded his head to be brought; ordered him to cut off his head in prison, and bring it away forthwith in a charger to him:
and he went and beheaded him in the prison; according to his orders.
