John 7
27 Ref However, it is clear to us where this man comes from: but when the Christ comes no one will have knowledge where he comes from.
28 Ref Then, when he was teaching in the Temple, Jesus said with a loud voice, You have knowledge of me and you have knowledge of where I come from; and I have not come of myself; but there is One who has sent me; he is true, but you have no knowledge of him.
29 Ref I have knowledge of him because I came from him and he sent me.
