וַיָּ֕שֶׁב אֵ֖ת כָּל־הָרְכֻ֑שׁ וְגַם֩ אֶת־ל֨וֹט אָחִ֤יו וּרְכֻשׁוֹ֙ הֵשִׁ֔יב וְגַ֥ם אֶת־הַנָּשִׁ֖ים וְאֶת־הָעָֽם׃
모든 빼앗겼던 재물과 자기 조카 롯과 그 재물과 또 부녀와 인민을 다 찾아왔더라
Or HaChaim
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
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.
