Matthew 14:26

22Immediately Jesus made the disciples get into the boat and go ahead of him to the other side, while he sent the multitudes away.

23After he had sent the multitudes away, he went up into the mountain by himself to pray. When evening had come, he was there alone.

24But the boat was now in the middle of the sea, distressed by the waves, for the wind was contrary.

25In the fourth watch of the night, Jesus came to them, walking on the sea.

26When the disciples saw him walking on the sea, they were troubled, saying, “It’s a ghost!” and they cried out for fear.

27But immediately Jesus spoke to them, saying, “Cheer up! It is I! Don’t be afraid.”

28Peter answered him and said, “Lord, if it is you, command me to come to you on the waters.”

29He said, “Come!” Peter stepped down from the boat and walked on the waters to come to Jesus.

30But when he saw that the wind was strong, he was afraid, and beginning to sink, he cried out, saying, “Lord, save me!”
