'Knowledge' in the Bible

I will give you shepherds according to my heart, who shall feed you with knowledge and understanding.

"For my people are foolish, they don't know me. They are foolish children, and they have no understanding. They are skillful in doing evil, but to do good they have no knowledge."

Every man is become brutish [and is] without knowledge; every goldsmith is disappointed by his engraved image; for his molten image is falsehood, and there is no breath in them.

Yahweh gave me knowledge of it, and I knew it: then you showed me their doings.

If I go forth into the field, then, behold, the slain with the sword! and if I enter into the city, then, behold, those who are sick with famine! for both the prophet and the priest go about in the land, and have no knowledge.

Every man is become brutish [and is] without knowledge; every goldsmith is disappointed by his image; for his molten image is falsehood, and there is no breath in them.
