Matthew 23:29
Woe to you, scribes and Pharisees, hypocrites! For you build the tombs of the prophets and decorate the monuments of the righteous. The eighth woe: the building and decorating of the prophets' tombs as an act of piety toward those their ancestors killed. The tomb-building communicates that the Pharisees consider themselves in a different moral category from those who killed the prophets — a self-assessment that Jesus will challenge.
