Matthew 14:24

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.

And in the fourth watch of the night Jesus went unto them, walking on the sea.

And when the disciples saw him walking on the sea, they were troubled, saying, It is a spirit; and they cried out for fear.
