John 6:18 YLT

¹⁶  And when evening came, his disciples went down to the sea,

¹⁷  and having entered into the boat, they were going over the sea to Capernaum, and darkness had already come, and Jesus had not come unto them,

¹⁸  the sea also -- a great wind blowing -- was being raised,

¹⁹  having pushed onwards, therefore, about twenty-five or thirty furlongs, they behold Jesus walking on the sea, and coming nigh to the boat, and they were afraid;

²⁰  and he saith to them, 'I am 'he', be not afraid;'
