8:19 My fruit is better than the purest gold,
and what I produce is better than choice silver.
10:20 What the righteous say is like the best silver,
but what the wicked think is of little value.
16:16 How much better it is to acquire wisdom than gold;
to acquire understanding is more desirable than silver.
17:3 The crucible is for refining silver and the furnace is for gold,
likewise the Lord tests hearts.
22:1 A good name is to be chosen rather than great wealth,
good favor more than silver or gold.
