Proverbs 13: 13 “Happy is the man that findeth wisdom, and the man that getteth understanding.
14 For the merchandise of it is better than the merchandise of silver, and the gain thereof than fine gold.
15 She is more precious than rubies: and all the things thou canst desire are not to be compared unto her.“
Proverbs 8:11 "For wisdom is better than rubies; and all the
things that may be desired are not to be compared to it."
Proverbs 16: “How much better is it to get wisdom than gold! and to get understanding rather to be chosen than silver!”
Proverbs 20:15 "There is gold, and a multitude of rubies:
but the lips of knowledge are a precious jewel."
