'Sense' in the Bible

"Let whoever is naive, turn in here." To anyone lacking sense, she says,

"Whoever is naive, turn in here!" And to anyone lacking sense, she says,

Whoever belittles his neighbor lacks sense, but the discerning man controls his comments.

Whoever tills his soil will have a lot to eat, but anyone who pursues fantasies lacks sense.

A man who lacks sense cosigns a loan, becoming a guarantor for his neighbor.
