Job 42:15 (ESV)

15 And in all the land there were no women so beautiful as Job’s daughters. And their father gave them an inheritance among their brothers.

Daughters were not normally given an inheritance, although in the law given to Moses, daughters had the right to inherit land if there were no sons to inherit it (Numbers 27:1–8).

The phrase among their brothers seems to suggest that Job’s property was equally divided between all ten his children, and that the seven brothers were satisfied with this arrangement. This serves to highlight the magnitude of Job’s wealth. A tenth of it was enough to satisfy every heir. It also illustrates the harmony between Job’s children, reminding us of the harmony that had existed between his first children (Job 1:4).
