'Knowledge' in the Bible

Hear the word of Yahweh, you children of Israel; for Yahweh has a charge against the inhabitants of the land: "Indeed there is no truth, nor goodness, nor knowledge of God in the land.

My people are destroyed for lack of knowledge. Because you have rejected knowledge, I will also reject you, that you may be no priest to me. Because you have forgotten your God's law, I will also forget your children.

For I desire mercy, and not sacrifice; and the knowledge of God more than burnt offerings.
