Matthew 23:30-33
23:30 And you say, ‘If we had lived in the days of our ancestors, we would not have participated with them in shedding the blood of the prophets.’
23:31 By saying this you testify against yourselves that you are descendants of those who murdered the prophets.
23:32 Fill up then the measure of your ancestors!
23:33 You snakes, you offspring of vipers! How will you escape being condemned to hell?
