Mattityahu 14:28-29

And Kefa said in reply to Rebbe, Melech HaMoshiach, Adoni, if it is really you, command me to come to you al pnei hamayim (on the surface of the waters). And Rebbe, Melech HaMoshiach said, Boh! (Come!) And having gone down from the sirah (boat), Kefa walked al pnei hamayim (on the surface of the waters) and came toward him.
