This week 2 is the third cycle of Pirkei Avos. In the second mishna of the third perek it says:
Rabban Gamliel the son of Rabbi Yehuda the Prince said, Torah study is good with a worldly occupation, because the exertion put into both of them makes one forget sin. All Torah without work will ultimately result in desolation and will cause sinfulness.
All who work for the community should work for the sake of Heaven, for the merit of the community’s forefathers will help them, and their righteousness endures forever. And as for you, God will reward you greatly as if you accomplished it on your own.
Commentary from Rabbi Goldson from this post on Aish:
Rabban Gamliel first taught that, even though there is no higher calling than Torah study, Torah will come to nothing unless it is channeled into positive action. We might think, therefore, that we must sacrifice some Torah in order to preserve the rest.
At the end of the Mishna, Rabban Gamliel assures us that directing Torah into positive action is the highest expression of Torah itself, whether that action takes the form of professional occupation or of extending oneself to benefit the community. There is no loss. Just the opposite: by taking time away from Torah to ensure the preservation of Torah values and ideals, we receive credit as if we had immersed ourselves in Torah without interruption. By taking time away from Torah study is in order to put Torah ideals into practice, then our reward will continue to multiply over and over again.
