'Knowledge' in the Bible

Hear the word of Jehovah, ye children of Israel; for Jehovah hath a controversy with the inhabitants of the land; for there is no truth, nor goodness, nor knowledge of God in the land.

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

For I delight in loving-kindness, and not sacrifice; and the knowledge of God more than burnt-offerings.
