Job 28:18 (ESV)

18 No mention shall be made of coral or of crystal; the price of wisdom is above pearls.

Job continues with his list of precious stones, thereby emphasizing that there is no earthly treasure that can compare with wisdom. This is true even of the wisdom that is accessible to man, the wisdom of everyday living (see Proverbs 3:15; Proverbs 8:11; Proverbs 16:16; Proverbs 20:15). How much more invaluable is that wisdom that understands all things!
