כי בגלל הדבר. אֲפִלּוּ אָמַרְתָּ לִתֵּן, אַתָּה נוֹטֵל שְׂכַר הָאֲמִירָה עִם שְׂכַר הַמַּעֲשֶׂה (שם): כי בגלל הדבר הזה BECAUSE THAT FOR THIS THING [THE LORD THY GOD SHALL BLESS THEE] — (the word is taken in its literal sense of “word”, for it would have sufficed to state כי בגלל זה suggesting): even if you only say (intend) to give but are later unable to do so you will receive a reward for the mere saying (intention) together with the reward for the action (Sifrei Devarim 117:8).
