'Wise Man' in the Bible

Better to hear a rebuke of a wise man, Than for a man to hear a song of fools,

The wisdom giveth strength to a wise man, more than wealth the rulers who have been in a city.

then I considered all the work of God, that man is not able to find out the work that hath been done under the sun, because though man labour to seek, yet he doth not find; and even though the wise man speak of knowing he is not able to find.

and there hath been found in it a poor wise man, and he hath delivered the city by his wisdom, and men have not remembered that poor man!
