Matthew 14:28-30

Young's Literal Translation

²⁸ And Peter answering him said, `Sir, if it is thou, bid me come to thee upon the waters;'

²⁹ and he said, `Come;' and having gone down from the boat, Peter walked upon the waters to come unto Jesus,

³⁰ but seeing the wind vehement, he was afraid, and having begun to sink, he cried out, saying, `Sir, save me.'
