be afraid, + exceedingly, fear, terror

Dictionary of Biblical Words:

is declared to be wisdom (Job. 28:28.) and the beginning of wisdom (Prov. 1:77The fear of the Lord is the beginning of knowledge: but fools despise wisdom and instruction. (Proverbs 1:7)). Its meaning may be expressed in the words of Psa. 16 “I have set the Lord always before me.” It consists in having God before one as the motive and governing principle of life. We get it in Acts 9:3131Then had the churches rest throughout all Judea and Galilee and Samaria, and were edified; and walking in the fear of the Lord, and in the comfort of the Holy Ghost, were multiplied. (Acts 9:31), as a character of Christian walk. The opposite to it is the fear of man which bringeth a snare. We are exhorted to walk in the fear of the Lord all the day long. See also Prov. 19:2323The fear of the Lord tendeth to life: and he that hath it shall abide satisfied; he shall not be visited with evil. (Proverbs 19:23).
