John Wesley on Joshua 24:7

Your eyes - He speaketh this to the elders, ver.1, who were so, not only by power and dignity, but many of them by age; and there being now not sixty years past since those Egyptian plagues, it is very probable that a considerable number of those present, had seen those things in Egypt, and being not twenty years old, were exempted from that dreadful sentence passed upon all who were older, Numb 14:29.
