Commentary for Psalms 44:4

כִּ֤י לֹ֪א בְחַרְבָּ֡ם יָ֥רְשׁוּ אָ֗רֶץ וּזְרוֹעָם֮ לֹא־הוֹשִׁ֪יעָ֫ה לָּ֥מוֹ כִּֽי־יְמִֽינְךָ֣ וּ֭זְרוֹעֲךָ וְא֥וֹר פָּנֶ֗יךָ כִּ֣י רְצִיתָֽם׃

For not by their own sword did they get the land in possession, Neither did their own arm save them; but Thy right hand, and Thine arm, and the light of Thy countenance, because Thou wast favourable unto them.

Rashi on Psalms
