John 9:28
“You are his disciple, but we are Moses' disciples.”
“But this cannot be. You are neither Moses' nor this Man's; for were ye Moses', you would become this Man's also.” Wherefore Christ before said unto them, because they were continually betaking themselves to these speeches, “Had ye believed Moses, you would have believed Me, for he wrote of Me.”
