'Smart' in the Bible

He that is surety for a stranger shall smart for it: and he that hateth suretiship is sure.

Walk with wise men, and thou shalt be wise; But the companion of fools shall smart for it.

Don't exhaust yourself acquiring wealth; be smart enough to stop.

I considered and observed on earth the following: The race doesn't go to the swift, nor the battle to the strong, nor food to the wise, nor wealth to the smart, nor recognition to the skilled. Instead, timing and circumstances meet them all.

For this reason whoever is smart keeps quiet in such a time, for it is an evil time.

Claiming to be wise, they became fools,

For you, being so wise, gladly put up with fools!
