וַיָּ֕שֶׁב אֵ֖ת כָּל־הָרְכֻ֑שׁ וְגַם֩ אֶת־ל֨וֹט אָחִ֤יו וּרְכֻשׁוֹ֙ הֵשִׁ֔יב וְגַ֥ם אֶת־הַנָּשִׁ֖ים וְאֶת־הָעָֽם׃
Und er brachte alle Habe zurück, auch seinen Verwandten Lot und dessen Habe brachte er zurück, und auch die Frauen und die Leute.
Sforno on Genesis
וגם את הנשים, he liberated Lot’s wives, as well as
Or HaChaim on Genesis
וגם את לוט ואת רכושו השיב, and he also restored Lot and his possessions. Although the whole exercise was designed only to rescue Lot, the Torah first reports Abraham's spectacular military accomplishments and how he restored their property to the five kings. The reason Abraham restored the women and children to the kings of Sodom was in recognition of the fact that they had treated Lot with respect and honour.
Radak on Genesis
וישב...וגם את לוט...וגם את הנשים ואת העם , they first of all restored all the captives to show that they had not killed any of them.
