Kiddush Hashem

Pinchas acts with total zeal for Hashem, and the Torah explains his reward, the Kehunah and the covenant of peace, by saying he turned back Hashem's anger from Bnei Yisrael. Why that reason, when the act was already a great Kiddush Hashem? The Steipler in Birkas Peretz looks at which mitzvos pay off even in this world. Rav Moshe Feinstein adds a second layer, with a little child helping his mother carry the groceries. Together they raise a question about where learning Torah fits in.
