Proverbs 1:7 The fear of the Lord is the beginning of Knowledge: but fools despise wisdom and instruction.
Wisdom means far more than just knowing a lot. A know it all is a person who has a dogmatic opinion about everything, is closed to anything new, resents discipline, and refuses to learn.
The Lord is the only one who does know it all. The foundation of knowledge is to fear the Lord- to honor and respect God, to live in aw of His power, and to obey His Word!
Genesis 1:28
