וְאֶת־כָּל־חֵילָ֤ם וְאֶת־כָּל־טַפָּם֙ וְאֶת־נְשֵׁיהֶ֔ם שָׁב֖וּ וַיָּבֹ֑זּוּ וְאֵ֖ת כָּל־אֲשֶׁ֥ר בַּבָּֽיִת׃
他們又擄走了他們所有的財物、所有的孩童和他們的妻子，並且搶奪了屋裡的一切。
Rashi
חילם means THEIR WEALTH. Examples are: (Deuteronomy 8:17) “hath gotten me this (חיל) wealth”; (Numbers 19:18) “and Israel acquireth (חיל) wealth”; (Psalms 49:11) “and they leave (חילם) their wealth to others”.
Siftei Chakhamim
From the term שבייה. The accent is, therefore, on the latter syllable. But if the accent was on the first syllable, like with קמו and שבו, the root would be שוב. Then it would mean “returning.”
Rashi
שבו has the meaning of taking captive (i.e. it is the Kal. perfect, 3rd pl. of the root שבה and means “they took captive”), and therefore it is accented on the last syllable (whereas שָׁבוּ, accented on the first syllable, is the same form of the verb שוב and means “they returned”).
