Thematic Bible: Strict obedience to superiors

And the captain in answer said, Lord, I am not good enough for you to come under my roof; but only say the word, and my servant will be made well. Because I myself am a man under authority, having under me fighting men; and I say to this one, Go, and he goes; and to another, Come, and he comes; and to my servant, Do this, and he does it.
