John 6:15-21 New Revised Standard Version, Anglicised (NRSVA)
15 When Jesus realized that they were about to come and take him by force to make him king, he withdrew again to the mountain by himself.
Jesus Walks on the Water
16 When evening came, his disciples went down to the lake, 17 got into a boat, and started across the lake to Capernaum. It was now dark, and Jesus had not yet come to them. 18 The lake became rough because a strong wind was blowing. 19 When they had rowed about three or four miles,[a] they saw Jesus walking on the lake and coming near the boat, and they were terrified. 20 But he said to them, ‘It is I;[b] do not be afraid.’ 21 Then they wanted to take him into the boat, and immediately the boat reached the land towards which they were going.
