jn 7:27-29
But we know where he is from. When the Messiah comes, no one will know where he is from." So Jesus cried out in the temple area as he was teaching and said, "You know me and also know where I am from. Yet I did not come on my own, but the one who sent me, whom you do not know, is true. I know him, because I am from him, and he sent me.".
