לְהוֹרִ֗ישׁ גּוֹיִ֛ם גְּדֹלִ֧ים וַעֲצֻמִ֛ים מִמְּךָ֖ מִפָּנֶ֑יךָ לַהֲבִֽיאֲךָ֗ לָֽתֶת־לְךָ֧ אֶת־אַרְצָ֛ם נַחֲלָ֖ה כַּיּ֥וֹם הַזֶּֽה׃
Para echar de delante de ti gentes grandes y más fuertes que tú, y para introducirte, y darte su tierra por heredad, como hoy.
Rashi on Deuteronomy
ממך מפניך — Invert it (the order of the words) and then explain it accordingly: to dispossess from before thee (מפניך) nations greater and mightier than thee (ממך)
Sforno on Deuteronomy
לתת לך את ארצם, which is really G’d’s favourite land, one that is always ready to help its inhabitants to achieve their perfection on earth.
Rashbam on Deuteronomy
כיום הזה, when you have already commenced the conquest by occupying the lands formerly owned by Sichon and Og.
