'Foolish' in the Bible

The proverbs of Solomon: A wise child makes a father glad, but a foolish child grieves his mother.

The {wisest of women} builds her house, but the foolish tears it down with her hands.

Leave {the presence of a foolish man}, [for] you will not [come to] know {words of knowledge}.

A child of wisdom will make a father glad, but a {foolish person}, he despises his mother.

A foolish child is a ruin to his father, and the quarreling of a woman is a continuous dripping.

Precious treasure and oil [are] in the house of the wise, but the foolish person will devour them.

[If] a wise man goes to court with a foolish man, then there is rankling and ridicule, but there is no relief.

If you have been foolish by exalting yourself, and if you have devised evil, [put your] hand to [your] mouth.
