John 1:47-51

Jesus saw Nathanael coming to him, and saith of him, Behold, an Israelite indeed, in whom is no guile! Nathanael saith unto him, Whence knowest thou me? Jesus answered and said unto him, Before Philip called thee, when thou wast under the fig tree, I saw thee. Nathanael answered him, Rabbi, thou art the Son of God; thou art King of Israel. Jesus answered and said unto him, Because I said unto thee, I saw thee underneath the fig tree, believest thou? thou shalt see greater things than these. And he saith unto him, Verily, verily, I say unto you, Ye shall see the heaven opened, and the angels of God ascending and descending upon the Son of man.
