Moses says, “And I commanded Joshua at that time, ‘Your eyes have seen all that the Lord your God has done to these two kings. So will the Lord do to all the kingdoms into which you are crossing. You shall not fear them, for it is the Lord your God who fights for you’” (Deuteronomy 3.21, 22). These two kings were also two giants, the text tells us. A generation earlier Joshua and Caleb were two witnesses (against ten) saying that they need not fear the giants in the land. Now we have two giants as witnesses by example, just outside the Land, that God will fight for them.
