Rashi on Exodus 3:1/רש"י על שמות ג׳:א׳

1אחר המדבר [HE LED THE SHEEP] BEHIND THE DESERT — in order to keep them away from private property (גֶזֵל i. e. things which can be appropriated only as the result of “robbery”) — that they should not graze in other people’s fields (Exodus Rabbah 2:3).

2אל הר האלהים TO THE MOUNTAIN OF GOD — Scripture so names it with reference to what happened there in the future (Sifrei on Deuteronomy 1:24).
