It cannot be gotten for gold, neither shall silver be weighed for the price thereof.
The gold and the crystal cannot equal it: and the exchange of it shall not be for jewels of fine gold.
For the merchandise of it is better than the merchandise of silver, and the gain thereof than fine gold.
Receive my instruction, and not silver; and knowledge rather than choice gold.
The tongue of the just is as choice silver: the heart of the wicked is little worth.
