Matthew 14:22-26 NIV

[22] Immediately Jesus made the disciples get into the boat and go on ahead of him to the other side, while he dismissed the crowd. [23] After he had dismissed them, he went up on a mountainside by himself to pray. Later that night, he was there alone, [24] and the boat was already a considerable distance from land, buffeted by the waves because the wind was against it. [25] Shortly before dawn Jesus went out to them, walking on the lake. [26] When the disciples saw him walking on the lake, they were terrified. “It’s a ghost,” they said, and cried out in fear.
