John 1: 47 - 51
47 Jesus saw Nathan'a-el coming to him, and said of him, "Behold, an Israelite indeed, in whom is no guile!"
48 Nathan'a-el said to him, "How do you know me?" Jesus answered him, "Before Philip called you, when you were under the fig tree, I saw you."
49 Nathan'a-el answered him, "Rabbi, you are the Son of God! You are the King of Israel!"
50 Jesus answered him, "Because I said to you, I saw you under the fig tree, do you believe? You shall see greater things than these."
51 And he said to him, "Truly, truly, I say to you, you will see heaven opened, and the angels of God ascending and descending upon the Son of man."
