Genesis 21:21

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).

וַיֵּ֖שֶׁב בְּמִדְבַּ֣ר פָּארָ֑ן וַתִּֽקַּֽח־ל֥וֹ אִמּ֛וֹ אִשָּׁ֖ה מֵאֶ֥רֶץ מִצְרָֽיִם׃ {פ}

And he dwelt in the wilderness of Paran: and his mother took him a wife out of the land of Miżrayim.
