'Unwise' in the Bible

Is this your answer to the Lord, O foolish people and unwise? Is he not your father who has given you life? He has made you and given you your place.

For they made his spirit bitter, and he said unwise things.

The wisdom of the man of good sense makes his way clear; but the unwise behaviour of the foolish is deceit.

Their wisdom is a crown to the wise, but their foolish behaviour is round the head of the unwise.

The heart of the man of good sense goes in search of knowledge, but foolish things are the food of the unwise.

Foolish behaviour is joy to the unwise; but a man of good sense makes his way straight.

He who has an unwise son gets sorrow for himself, and the father of a foolish son has no joy.

Be not unwise with your mouth, and let not your heart be quick to say anything before God, because God is in heaven and you are on the earth--so let not the number of your words be great.

The pains of a woman in childbirth will come on him: he is an unwise son, for at this time it is not right for him to keep his place when children come to birth.
