'Smart' in the Bible

He who puts up security and guarantees a debt for an outsider will surely suffer [for his foolishness],But he who hates (declines) being a guarantor is secure [from its penalties].

He who walks [as a companion] with wise men will be wise,But the companions of [conceited, dull-witted] fools [are fools themselves and] will experience harm.

Claiming to be wise, they became fools,

For you, being so wise, gladly tolerate and accept the foolish [like me]!
