John 1:51 YLT

⁴⁹  Nathanael answered and saith to him, 'Rabbi, thou art the Son of God, thou art the king of Israel.'

⁵⁰  Jesus answered and said to him, 'Because I said to thee, I saw thee under the fig-tree, thou dost believe; greater things than these thou shalt see;'

⁵¹  and he saith to him, 'Verily, verily, I say to you, henceforth ye shall see the heaven opened, and the messengers of God going up and coming down upon the Son of Man.'
