'Foolish' in the Bible

Deliver me from all my transgressions. Don't make me the reproach of the foolish.

This is the destiny of those who are foolish, and of those who approve their sayings. Selah.

Remember this, that the enemy has mocked you, Yahweh. Foolish people have blasphemed your name.

Arise, God! Plead your own cause. Remember how the foolish man mocks you all day.
