Y toda su hacienda; se llevaron cautivos á todos sus niños y sus mujeres, y robaron todo lo que había en casa.
Rashi on Genesis
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”.
Radak on Genesis
ואת כל חילם, silver, gold , and precious stones.
