וְעָבַ֣ר עַצְמ֗וֹנָה וְיָצָא֙ נַ֣חַל מִצְרַ֔יִם והיה [וְהָי֛וּ] תֹּצְא֥וֹת הַגְּב֖וּל יָ֑מָּה זֶה־יִהְיֶ֥ה לָכֶ֖ם גְּב֥וּל נֶֽגֶב׃
거기서 아스몬에 이르고 애굽 시내에 미치며 바다에 이르러 경계의 끝이 되나니 이것이 너희 남편 경계가 되리라
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.
