When you are kind enough to help the Jews on their Saturday Sabbath,
so that the Jews don't have to work, the Jews call you, "Sabbath Dirt" behind your back.
The Jews want you to work for them on Saturdays to make their own rules less onerous for them, but to show their
hatred and contempt for you,
even their little parasitic larva call you bad names behind your back.
"All the favours of the wicked [you], are evil for the righteous [them].
(Babylonian Talmud, Yevamoth 103a-103b)
So if you are kind to the Jews or do them any favors, they hate you for it;
behind your back, of course, because they want you to keep doing them favors.
