Matthew 23:29-31

29“Woe to you, teachers of the law and Pharisees, you hypocrites! You build tombs for the prophets and decorate the graves of the righteous. 30And you say, ‘If we had lived in the days of our ancestors, we would not have taken part with them in shedding the blood of the prophets.’ 31So you testify against yourselves that you are the descendants of those who murdered the prophets.
