And he said, "Woe to you lawyers also! for you load men with burdens hard to bear, and you yourselves do not touch the burdens with one of your fingers. Woe to you! for you build the tombs of the prophets whom your fathers killed. So you are witnesses and consent to the deeds of your fathers; for they killed them, and you build their tombs. Therefore also the Wisdom of God said, 'I will send them prophets and apostles, some of whom they will kill and persecute,' that the blood of all the prophets, shed from the foundation of the world, may be required of this generation, from the blood of Abel to the blood of Zechari'ah, who perished between the altar and the sanctuary. Yes, I tell you, it shall be required of this generation.
-- Luke 11:46ff.
