Proverbs 17:2 KJV — A wise servant shall have rule over a son that causeth shame, and shall have part of the inheritance among the brethren.
From a servant to an heir.
Wisdom trumps biology and heritage.
Regardless of the system of discrimination, caste and hierarchy, wisdom is the key to transcending one’s “station”.
No matter where you start, wisdom is the key to promotion and transcendence.
