'Essence' in the Bible

"Can you discover the essence of God? Can you find out the perfection of the Almighty?

The [reverent] fear of the Lord [that is, worshiping Him and regarding Him as truly awesome] is the beginning and the preeminent part of knowledge [its starting point and its essence];But arrogant fools despise [skillful and godly] wisdom and instruction and self-discipline.

No one remembers, nor has knowledge and understanding [enough] to say [to himself], “I have burned half of this log in the fire, and also baked bread on its coals and have roasted meat and eaten it. Then I make the rest of it into an repulsive thing [to God]; I bow down [to worship] before a block of wood!”
