Don

The masculine plural is used in Hebrew and Greek when a group is composed of at least 1 male, all the way up to all males.  So the context is important to see whether a term is best translated as sons or children.

IF the culture was such that only males inherited, then it might be important to translate as sons.  We see with the daughters of Zelophehad in Numbers 36 in a very patriarchical culture.  But the culture shifts, it did not stay that way in Roman areas, for example.
