'Knowledge' in the Bible

"Hear this message from the LORD, people of Israel. Indeed, the LORD brings a charge against the people who live in the land for there is no truth and no gracious love or knowledge of God in the land.

My people are destroyed because they lack knowledge of me. Because you rejected that knowledge, I will reject you as a priest for me. Since you forget the Law of your God, I will also forget your children.

Let us know, let us pursue knowledge of the LORD; his coming is as certain as the dawn. He will come to us like the rain, like the autumn and spring rains come on the earth.

For it is love that I seek, and not sacrifice; knowledge of God more than burnt offerings.
