'Lack Of Knowledge' in the Bible

Therefore my people are gone into captivity for lack of knowledge; and their honorable men are famished, and their multitude are parched with thirst.

Every man is stupid for lack of knowledge; every refiner is put to shame by the graven image; for his molten image is a lie, and no breath is in them.

My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children.
