John 3:11-13

Young's Literal Translation

¹¹ `Verily, verily, I say to thee -- What we have known we speak, and what we have seen we testify, and our testimony ye do not receive;

¹² if the earthly things I said to you, and ye do not believe, how, if I shall say to you the heavenly things, will ye believe?

¹³ and no one hath gone up to the heaven, except he who out of the heaven came down -- the Son of Man who is in the heaven.
