Speech delivered by Hitler in Salzburg, 7 or 8 August 1920. (NSDAP meeting)
And here is one thing that perhaps distinguishes us from you [Austrians] as far as our programme is concerned, although it is very much in the spirit of things: our attitude to the Jewish problem.
For us, this is not a problem you can turn a blind eye to-one to be solved by small concessions. For us, it is a problem of whether our nation can ever recover its health, whether the Jewish spirit can ever really be eradicated. Don't be misled into thinking you can fight a disease without killing the carrier, without destroying the bacillus. Don't think you can fight racial tuberculosis without taking care to rid the nation of the carrier of that racial tuberculosis. This Jewish contamination will not subside, this poisoning of the nation will not end, until the carrier himself, the Jew, has been banished from our midst.
(Applause)

Hitler's Conversation with Josef Hell, 1922
When Hell asked Hitler what he intended doing if he ever had full freedom of action against the Jews, his response was:
"If I am ever really in power, the destruction of the Jews will be my first and most important job. As soon as I have power, I shall have gallows after gallows erected, for example, in Munich on the Marienplatz-as many of them as traffic allows. Then the Jews will be hanged one after another, and they will stay hanging until they stink. They will stay hanging as long as hygienically possible. As soon as they are untied, then the next group will follow and that will continue until the last Jew in Munich is exterminated. Exactly the same procedure will be followed in other cities until Germany is cleansed of the last Jew!"
(quoted in John Toland, Adolf Hitler. London: Book Club Associates, 1977, p.116)
