'Foolish' in the Bible

Do you thus requite Yahweh, foolish people and unwise? Isn't he your father who has bought you? He has made you, and established you.

They have moved me to jealousy with that which is not God. They have provoked me to anger with their vanities. I will move them to jealousy with those who are not a people. I will provoke them to anger with a foolish nation.
