For wisdom is better than rubies; and all things that may be desired are not to be compared to it.
– Proverbs 8:11
Silver, gold, and precious stones have a sort of intrinsic value and rarity. They are the pinnacle of objective value, though all men esteem them not equally. All things that may be desired is more subjective but expands the range of prized things to include anything a man may prize. These are things men give their life for to obtain. On all accounts, wisdom is more surpassingly valuable than anything highly prized among men. It follows that men should search more diligently and attend more immediately to wisdom than all earthly riches.
