וְעָבַ֣ר עַצְמ֗וֹנָה וְיָצָא֙ נַ֣חַל מִצְרַ֔יִם והיה [וְהָי֛וּ] תֹּצְא֥וֹת הַגְּב֖וּל יָ֑מָּה זֶה־יִהְיֶ֥ה לָכֶ֖ם גְּב֥וּל נֶֽגֶב׃
E passou por Atzmotá, e saiu pelo rio de Mitzrayim, e as saídas do limite serão até o mar Ocidental; este será para vós o limite do sul.
Rashi
“Your left side” symbolizes Samaria; “your right side” symbolizes Judah, because Judah is in the south of the land of Israel, as it is said (16:46): “And your big sister Samaria...who lives at your left.” Also in the Book of Joshua (15:1), he describes the border of the tribe of Judah as occupying the entire southern border.
