Bede the Venerable

Then answered one of the Lawyers, and said unto him, Master, thus saying thou reproachest us also. And he said, Woe unto you also, ye Lawyers! for ye lade men with burdens grievous to be borne, and ye yourselves touch not the burdens with one of your fingers. Woe unto you! for ye build the sepulchres of the prophets, and your fathers killed them. Truly ye bear witness that ye allow the deeds of your fathers: for they indeed killed them, and ye build their sepulchres. Therefore also said the wisdom of God, I will send them prophets and apostles, and some of them they shall slay and persecute: That the blood of all the prophets, which was shed from the foundation of the world, may be required of this generation; From the blood of Abel unto the blood of Zacharias, which perished between the altar and the temple: verily I say unto you, It shall be required of this generation. Woe unto you, Lawyers! for ye have taken away the key of knowledge: ye enter not in yourselves, and them that were entering in ye hindered. And as he said these things unto them, the Scribes and Pharisees began to urge him vehemently, and to provoke him to speak of many things: Laying wait for him, and seeking to catch something out of his mouth, that they might accuse him. It follows, Woe to you, lawyers, for ye have taken away the key of knowledge.
