וְנָסַ֧ב הַגְּב֛וּל מֵעַצְמ֖וֹן נַ֣חְלָה מִצְרָ֑יִם וְהָי֥וּ תוֹצְאֹתָ֖יו הַיָּֽמָּה׃
Dari Azmon batas itu akan berbelok ke Wadi Mesir, dan ujungnya akan berada di laut.
Rashi
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
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.
