John Gill's Bible Commentary Ver. 9. For I am a man under authority , etc.] Of Caesar the Roman emperor, and of superior officers under him, as a tribune, etc. having soldiers under me ; an hundred of them at least, for military service, and some of them were used by him as his domestics: and I say unto this man go, and he goeth, and to another come, and he cometh : for there is no disputing the commands of officers, by soldiers, in anything, in exercises, marches, battles, etc. and to my servant , that was more properly his domestic servant, who waited upon him, and did those things for him which every soldier under him was not employed in, do this, and he doth it ; immediately, without any more ado; as indeed a servant ought. The Jews have a saying, that a servant over whom his master twr ya , hath no power, is not called a servant.
Now, these words are not a reason excusing Christs coming to his house, or showing how unworthy it was, and how unfit it would be for him to come thither, since he was a man that held soldiers under him, and his house was encumbered with them; for these were not with him, but quartered out elsewhere: but they are an argument, from the lesser to the greater, that seeing he was a man, and Christ was God, he was under the authority of others. Christ was subject to none; and yet he had such power over his soldiers and servants, that if he bid one go, and another come, or ordered them to stand in such a place, and in such a posture, or do this and the other servile work, his orders were immediately obeyed: how much more easily then could Christ, who had all power in heaven and in earth, command off this distemper his servant was afflicted with? He suggests, that as his soldiers were under him, and at his command; so all bodily diseases were under Christ, and to be controlled by him, at his pleasure; and that, if he would but say to that servant of his, the palsy, remove, it would remove at once.
Matthew Henry Commentary
Verses 5-13 - This centurion was a heathen, a Roman soldier. Though he was a soldier yet he was a godly man. No man's calling or place will be an excuse for unbelief and sin. See how he states his servant's case. We shoul concern ourselves for the souls of our children and servants, who ar spiritually sick, who feel not spiritual evils, who know not that whic is spiritually good; and we should bring them to Christ by faith an prayers. Observe his self-abasement. Humble souls are made more humbl by Christ's gracious dealings with them. Observe his great faith. The more diffident we are of ourselves, the stronger will be our confidenc in Christ. Herein the centurion owns him to have Divine power, and full command of all the creatures and powers of nature, as a maste over his servants. Such servants we all should be to God; we must go and come, according to the directions of his word and the disposals of his providence. But when the Son of man comes he finds little faith therefore he finds little fruit. An outward profession may cause us to be called children of the kingdom; but if we rest in that, and have nothing else to show, we shall be cast out. The servant got a cure of his disease, and the master got the approval of his faith. What wa said to him, is said to all, Believe, and ye shall receive; onl believe. See the power of Christ, and the power of faith. The healin of our souls is at once the effect and evidence of our interest in the blood of Christ.

Vincent's NT Word Studies
9. Also (kai). Omitted in A.V., but very important. "I also am a man under authority," as well as thou. (Tynd., I also myself). The centurion compares the Lord's position with his own. Christ had authority over disease. The centurion also was in authority over soldiers. As the centurion had only to say to a soldier "Go!" and he went, so Christ had only to say to disease "Go!" and it would obey him.
Robertson's NT Word Studies
8:9 {For I also am a man under authority} (kai gar egw anqrwpos hupo exousian). "Also" is in the text, though the kai here may mean "even," even I in my subordinate position have soldiers under me. As a military man he had learned obedience to his superiors and so expected obedience to his commands, instant obedience (aorist imperatives and aoristic present indicatives). Hence his faith in Christ's power over the illness of the boy even without coming. Jesus had only to speak with a word (#8:8), say the word, and it would be done.
