In 1933 about 45 million of Germany's 65 million or so people were Protestant, so there were a lot of them. Luther's recommendations in his treatise On the Jews and Their Lies for how Christians should treat the least of these my brethren, the Jews, was fully implemented and creatively enhanced.
Are you certain the Jews were not killed and persecuted because of this?
"For I know thy rebellion, and thy stiff neck: behold, while I am yet alive with you this day, ye have been rebellious against the Lord; and how much more after my death? Gather unto me all the elders of your tribes, and your officers, that I may speak these words in their ears, and call heaven and earth to record against them. For I know that after my death ye will utterly corrupt yourselves, and turn aside from the way which I have commanded you; and evil will befall you in the latter days; because ye will do evil in the sight of the Lord, to provoke him to anger through the work of your hands." (Deu 31:27-29)
Or, maybe this?
"Moreover all these curses shall come upon thee, and shall pursue thee, and overtake thee, till thou be destroyed; because thou hearkenedst not unto the voice of the Lord thy God, to keep his commandments and his statutes which he commanded thee: And they shall be upon thee for a sign and for a wonder, and upon thy seed for ever. Because thou servedst not the Lord thy God with joyfulness, and with gladness of heart, for the abundance of all things;" (Deu 28:45-47)
David:
"Make a joyful noise unto the Lord, all ye lands. Serve the Lord with gladness: come before his presence with singing. (Psalms 100:1-2)
