For he selected this one nation to teach the knowledge of God to all the others. Just as he had selected one man—at one time Moses, at another Joshua, at another Samuel, at another some other of the prophets—to look after the welfare of this race, one man who benefited his fellows by practicing true wisdom, so through the one race, Israel, he called all the races of the earth that shared the same nature to share the same religion.
