Matthew 8:9

For I am a man under authority - That is, under the authority of others. This verse has given considerable embarrassment to commentators and critics. I believe the paraphrase given above to be the true meaning of the evangelist. To make this matter more plain, let it be observed, that the Roman foot was divided into three grand parts, Hastati, Principes, and Triarii. Each of these grand divisions was composed of thirty manipuli or companies; and every manipulus made two centuries or companies of one hundred men. Every manipulus had two centurions; but these were very far from being equal in rank and honor, though possessing the very same office. The Triarii and Principes were esteemed the most honorable, and had their centurions elected first; and these first elected centurions took precedency of the centurions of the Hastati, who were elected last. The centurion in the text was probably one of this last order; he was under the authority of either the Principes or Triarii, and had none under him but the hundred men whom he commanded, and who appear to have been in a state of the most loving subjection to him. The argument of the centurion seems to run thus. If I, who am a person subject to the control of others, yet have some so completely subject to myself, that I can say to one, Come, and he cometh, to another, Go, and he goeth, and to my slave ( τω δουλω μου ) Do this, and he doeth it; how much more then canst thou accomplish whatsoever thou willest, being under no control, and having all things under thy command: He makes a proper use of his authority, who, by it, raises his mind to the contemplation of the sovereign power of God, taking occasion from it to humble himself before Him who has all power in heaven and earth, and to expect all good from him.

There are two beautiful passages in Arrian that tend much to illustrate this speech of the centurion.

Καταταγεις Αγαμεμνων, λεγει μοι, πορευου προς τον Αχιλλεα, και αποσπασον την Βρισηιδα, πορευομαι. Ερχου, ερχομαι .

"He who personates Agamemnon says to me, Go to Achilles, and bring hither Briseis: I go. He says, Come hither: I come."
