Matthew 14:22-26

22And immediately Jesus constrained his disciples to get into a boat, and to go before him to the other side, while he sent the multitudes away. 23And when he had sent the multitudes away, he went up to a mountain by himself to pray: and when the evening was come, he was there alone. 24But the boat was now in the midst of the sea, tossed with waves: for the wind was contrary. 25And in the fourth watch of the night Jesus went to them, walking on the sea. 26And when the disciples saw him walking on the sea, they were troubled, saying, It is a ghost; and they cried out for fear.
