Proverbs 1:5 A wise man will hear, and will increase learning; and a man of understanding shall attain unto wise counsels:

1 Timothy 4:12 Let no man despise thy youth; but be thou an example of the believers, in word, in conversation, in charity, in spirit, in faith, in purity.

1 Corinthians 10:15 I speak as to wise men; judge ye what I say.

1 Corinthians 14:20 Brethren, be not children in understanding: howbeit in malice be ye children, but in understanding be men.
