Performing mitzvos

Chazal tell us (Kidushin 39b), "Schar Mitzva B'Hai Alma Leka", there is no reward for Mitzvos in this world, only in the next.  The pasuk by Tzedaka (Re'eh 15:10) seems to contradict this as it says נָתוֹן תִּתֵּן לוֹ, וְלֹא-יֵרַע לְבָבְךָ בְּתִתְּךָ לוֹ כִּי בִּגְלַל הַדָּבָר הַזֶּה, יְבָרֶכְךָ יְהוָה אֱלֹהֶיךָ, בְּכָל-מַעֲשֶׂךָ.  If we give Tzedaka Hashem will give a bracha to all our work.  Is there reward in this world or not?

The Ksav Sofer answers that for the mitzva itself there is no reward in this world.  However for the Simcha, the joy with which you do the Mitzva, there is a reward in this world.  If we look carefully at the pasuk we see that the pasuk clearly says this. נָתוֹן תִּתֵּן לוֹ, give tzedaka.  וְלֹא-יֵרַע לְבָבְךָ בְּתִתְּךָ לוֹ, there should be no ill will in your heart when you give it, only joy in doing Hashem's mitzva. כִּי בִּגְלַל הַדָּבָר הַזֶּה, יְבָרֶכְךָ יְהוָה אֱלֹהֶיךָ, בְּכָל-מַעֲשֶׂךָ, because of this aspect of the mitzva , the simcha you had, you will be rewarded in this world.

Hamodia has an editorial titled More Ammunition is Needed.


Many of us spend much time closely following, discussing, and analyzing current developments in Eretz Yisrael. It would be highly beneficial to take some of that precious time and dedicate it to doing something practical on their behalf. Every moment of learning Torah, every perek Tehillim that is recited, and every mitzvah that is performed, arouses great zechuyos and provides desperately needed ammunition in Shamayim.

Our brethren in Eretz Yisrael are relying on us. We dare not turn them down.
