New Defender's Study Bible Notes
4:17 father of many nations. This promise (Genesis 17:5) has been literally fulfilled, as well as spiritually. Abraham is the ancestor not only of the Israelites, but also of all the Arabic nations, as well as the Edomites, Midianites and others that are now either extinct or amalgamated with others. Probably most of the Middle Eastern Islamic nations have at least some degree of genetic descent from Abraham.
