Matthew 23:29-31

29 "Woe to you, scribes and Pharisees, hypocrites! For you build the tombs of the prophets and decorate the graves of the righteous,

30 and 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.'

31 Thus you testify against yourselves that you are descendants of those who murdered the prophets.
