For I am a man under authority] If I, being under command of others, yet having others under my command, can thus do; thou, who hast absolute command, much more. Thus men should take occasion, from their own power over others, and their ready subjection to them, to take notice of Gods sovereign authority over themselves, and be ready to obey him in all things.
Go, and he goeth] Not questioning why or wherefore, but, without sticking or stay, oing what is enjoyned: so will this sicknesse be gone, at thy command.
