The ancient Hebrews were just into cultural racism as all the other ancient civilizations of their era.
It was done so by the Hebrews to create an up level stature as a civilization as a nation chosen exclusively by the Grand Creator god of the universe.(YHWH)
Their mythology was to connect themselves in a relationship to the highest or the Almighty god of the universe.
This intent also made them distinct and unique among other civilizations.
JWs today claim that they have been chosen by god Jehovah (1919) because their organization has adhered the closest to Scripture, therefore are in more appeasement to god through their unique doctrinal teachings, well they aren't because in reality they are just false commercialized prophets .
