Verses 3, 4 – Women did not traditionally inherit property in Israelite society, but Moses put what was the right thing to do over tradition (Numbers 27:1-11). In fact, God told Moses to add a law that would help other women in similar circumstances inherit property as well. This rings true in so many situations today; people refuse to honor a reasonable request because “we have never done it that way before.” However, Joshua honored what Moses had written.
Verses 14, 15 – Caleb took what God gave him and moved ahead with fulfilling that purpose in the land (verses 14:12). He was confident God would help him drive the inhabitants out. In contrast, the two tribes of Joseph were given rich land and lots of it, but yet were afraid of the inhabitants that they needed to drive out, instead they simply asked for more land. However, Joshua asked them to prove their sincerity first by clearing the unclaimed forest areas. They agreed, but failed to carry through what was required of them (judges 1:27).
