Taken and added word warnings Luke 11:52 Woe unto you, lawyers! for ye have taken away the key of knowledge: ye entered not in yourselves, and them that were entering in ye hindered. Gospel of Thomas 39 (39) Jesus said: The Pharisees and the scribes have taken the keys of knowledge (and) have hidden them. They did not go in, and those who wished to go in they did not allow. But you, be wise as serpents and innocent as doves. Matthew 16:12 12 Then the disciples understood that he was not warning them to guard themselves from the yeast used in bread but from the teaching of the Pharisees and Sadducees.
