וְנָסַ֧ב הַגְּב֛וּל מֵעַצְמ֖וֹן נַ֣חְלָה מִצְרָ֑יִם וְהָי֥וּ תוֹצְאֹתָ֖יו הַיָּֽמָּה׃
아스몬에서 돌아서 애굽 시내를 지나 바다까지 이르느니라
Rashi on Numbers
והיו תוצאותיו הימה AND ITS GOINGS OUT SHALL BE AT THE SEA i.e. at the western boundary, because the southern border does not extend any more west of there and further on.
Rashbam on Numbers
והיו תוצאותיו הימה, the whole boundary there forms a southern-westerly wedge, apex.
Rabbeinu Bahya
נחלה מצרים, “to the stream of Egypt.” This means: “to the river dividing Egypt from Palestine,” and not to the river Nile.
