Job 28:15-19

Pure gold cannot be given in exchange for it, Nor can silver be weighed as its price. It cannot be valued in the gold of Ophir, In precious onyx, or sapphire. Gold or glass cannot equal it, Nor can it be exchanged for articles of fine gold. Coral and crystal are not to be mentioned; And the acquisition of wisdom is above that of pearls. The topaz of Ethiopia cannot equal it, Nor can it be valued in pure gold.
