'Unwise' in the Bible

“Does the ear not put words to the test,Just as the palate tastes its food [distinguishing between the desirable and the undesirable]?

The pains of childbirth come on him;But he is not a wise son,For it is not the time to delay [his chance at a new birth] as the womb opens [but he ignores the opportunity to change].

Therefore see that you walk carefully [living life with honor, purpose, and courage; shunning those who tolerate and enable evil], not as the unwise, but as wise [sensible, intelligent, discerning people],
