Matthew 14:22-25

And straightway Jesus constrained his disciples to get into a ship, and to go before him unto the other side, while he sent the multitudes away. And when he had sent the multitudes away, he went up into a mountain apart to pray: and when the evening was come, he was there alone. But the ship was now in the midst of the sea, tossed with waves: for the wind was contrary. And in the fourth watch of the night Jesus went unto them, walking on the sea.
