Matthew 23:29-31

29Woe to you, scribes and Pharisees, you hypocrites! You build tombs for the prophets and decorate the monuments of the righteous. 30And you say, ‘If we had lived in the days of our fathers, we would not have been partners with them in shedding the blood of the prophets.’ 31So you testify against yourselves that you are the sons of those who murdered the prophets.
