47 When Jesus saw Nathanael coming he said of him, ‘There, truly, is an Israelite in whom there is no deception.’
48 Nathanael asked, ‘How do you know me?’ Jesus replied, ‘Before Philip came to call you, I saw you under the fig tree.’
49 Nathanael answered, ‘Rabbi, you are the Son of God, you are the king of Israel.’
50 Jesus replied, ‘You believe that just because I said: I saw you under the fig tree. You are going to see greater things than that.’
I don’t understand that Jesus seeing him under a tree astonishes Nathanael, did he see him earlier in the day or was the fig tree on the other side of the city?
