i abjure you by the living god , who has shown forth the tree of life , and posted the cherubim , and the flaming sword that turns about to guard this : be rebuked , and depart , for i forbid you , through him that walks on the waves of the sea as upon the dry land , who forbade the storm of the winds , whose glance dries up the deep , and whose threatenings melt the mountains ; for it is he himself that now forbids you through us .
