What is the fear of the Lord?

Psalms 34:11-14 11 Come, O children, listen to me; I will teach you the fear of the LORD. 12 What man is there who desires life and loves many days, that he may see good? 13 Keep your tongue from evil and your lips from speaking deceit. 14 Turn away from evil and do good; seek peace and pursue it. "David is saying that the fear of the Lord is doing right, that is, that it involves obedience. Moreover, since the fear of the Lord is the enjoyment of the Lord, the way to enjoy the Lord, to “taste and see that [he] is good,” is to obey him. One commentator explains this by saying, “The good you enjoy (v. 12) goes hand in hand with the good you do (v. 14). It is an emphasis which answers the suspicion (first aroused in Eden) that outside the will of God, rather than within it, lies enrichment.”" James Montgomery Boice
