'Best' in the Bible

so that you don't give your honor to others, and waste your best years;

Take my teaching, and not silver; get knowledge in place of the best gold.

My fruit is better than gold, even than the best gold; and my increase is more to be desired than silver.

What the righteous say is like the best silver, but what the wicked think is of little value.

He who covers an offense promotes love; but he who repeats a matter separates best friends.

Like a nose-ring of gold and an ornament of the best gold, is a wise man who says sharp words to an ear ready to give attention.
