'Fool' in the Bible

But I say to you that everyone who is angry at his brother will be subject to judgment, and whoever says to his brother, 'Stupid fool!' will be subject to the council, and whoever says, 'Obstinate fool!' will be subject to fiery hell.

But God said to him, 'Fool! This night your life is demanded from you, and [the things] which you have prepared--whose will they be?'

Let no one deceive himself. If anyone thinks [himself] to be wise among you in this age, let him become a fool, in order that he may become wise.

I have become a fool! You compelled me, for I ought to have been commended by you, for [I am] in no way inferior to the preeminent apostles, even if I am nothing.
