That's the people's words, not God's words. The Kenites killed Jesus, not the seed of Judah.
Tell me this. If you were to see a venerable man, illustrious and renowned, dragged off into a tavern or den of robbers; if you were to see him outraged, beaten, and subjected there to the worst violence, would you have held that tavern or den in high esteem because that great and esteemed man had been inside it while undergoing that violent treatment? I think not. Rather, for this very reason you would have hated and abhorred the place.
Let that be your judgment about the synagogue, too. For they brought the books of Moses and the prophets along with them into the synagogue, not to honor them but to outrage them with dishonor. When they say that Moses and the prophets knew not Christ and said nothing about his coming, what greater outrage could they do to those holy men than to accuse them of failing to recognize their Master, than to say that those saintly prophets are partners of their impiety? And so it is that we must hate both them and their synagogue all the more because of their offensive treatment of those holy men.
Why do I speak about the books and the synagogues? In time of persecution, the public executioners lay hold of the bodies of the martyrs, they scourge them, and tear them to pieces. Does it make the executioners' hands holy because they lay hold of the body of holy men? Heaven forbid! The hands which grasped and held the bodies of the holy ones still stay unholy. Why? Because those executioners did a wicked thing when they laid their hands upon the holy. And will those who handle and outrage the writings of the holy ones be any more venerable for this than those who executed the martyrs? Would that not be the ultimate foolishness? If the maltreated bodies of the martyrs do not sanctify those who maltreated them but even add to their blood-guilt, much less could the Scriptures, if read without belief, ever help those who read without believing. The very act of deliberately choosing to maltreat the Scriptures convicts them of greater godlessness.
If they did not have the prophets, they would not deserve such punishment; if they had not read the sacred books, they would not be so unclean and so unholy. But, as it is, they have been stripped of all excuse. They do have the heralds of the truth but, with hostile heart, they set themselves against the prophets and the truth they speak. So it is for this reason that they would be all the more profane and blood-guilty: they have the prophets, but they treat them with hostile hearts.
