'Fools' in the Bible

Only, fools are the princes of Zoan, The counsel of the wise ones of the counsellors of Pharaoh hath become brutish. How say ye unto Pharaoh, 'A son of the wise am I, a son of kings of antiquity?'

And a highway hath been there, and a way, And the 'way of holiness' is called to it, Not pass over it doth the unclean, And He Himself is by them, Whoso is going in the way -- even fools err not.
