Well, tzedaka taztil mimaves. The gemera says so.
Aser bishvil shetisasher. That is not a 21st century advertising slogan.
Arba shelach, kineged arba sheli. That is a rashi on a passuk in chumash. Not a madison avenue marketing campaign.
Tzedaka is the only time we are allowed to “test” hashem. This is a gemara.
do these maamarei chazal turn you off to the mitzva of tzedaka?
