There is no other explanation for this than the one cited earlier from Moses — namely, that God has struck [the Jews] with 'madness and blindness and confusion of mind.' So we are even at fault in not avenging all this innocent blood of our Lord and of the Christians which they shed for three hundred years after the destruction of Jerusalem, and the blood of the children they have shed since then (which still shines forth from their eyes and their skin). We are at fault in not slaying them. Rather we allow them to live freely in our midst despite all their murdering, cursing, blaspheming, lying, and defaming; we protect and shield their synagogues, houses, life, and property. In this way we make them lazy and secure and encourage them to fleece us boldly of our money and goods, as well as to mock and deride us, with a view to finally overcoming us, killing us all for such a great sin, and robbing us of all our property (as they daily pray and hope). Now tell me whether they do not have every reason to be the enemies of us accursed
Goyim, to curse us and to strive for our final, complete, and eternal ruin!
