וְשָׂרַי֙ אֵ֣שֶׁת אַבְרָ֔ם לֹ֥א יָלְדָ֖ה ל֑וֹ וְלָ֛הּ שִׁפְחָ֥ה מִצְרִ֖ית וּשְׁמָ֥הּ הָגָֽר׃
아브람의 아내 사래는 생산치 못하였고 그에게 한 여종이 있으니 애굽 사람이요 이름은 하갈이라

מארץ מצרים FROM THE LAND OF EGYPT — from the place where she was brought up — as it is said (16:1) “And she (Sarah) had an Egyptian handmaid [whose name was Hagar]”. That is what the popular proverb says: “Throw a stick into the air and it will fall back to (literally, stand on) its element” (Genesis Rabbah 53:15).
