בראשית 22:19

וישב אברהם בבאר שבע AND ABRAHAM DWELT AT BEER-SHEBA — This does not mean really dwelling there but merely staying there on his way home, because he was, as a matter of fact, living at Hebron. Twelve years before the Binding of Isaac he had left Beer-Sheba and had gone to Hebron, as it is said, (21:34) ‘‘And Abraham sojourned in the land of the Philistines many days”, i.e. exceeding in number the earlier days when he had resided at Hebron — altogether 26 years, as we have explained above (21:34).

וַיָּ֤שׇׁב אַבְרָהָם֙ אֶל־נְעָרָ֔יו וַיָּקֻ֛מוּ וַיֵּלְכ֥וּ יַחְדָּ֖ו אֶל־בְּאֵ֣ר שָׁ֑בַע וַיֵּ֥שֶׁב אַבְרָהָ֖ם בִּבְאֵ֥ר שָֽׁבַע׃ {פ}

So Avraham returned to his young men, and they rose up and went together to Be᾽er-sheva; and Avraham dwelt at Be᾽er-sheva.
