Proverbs 9:10 says, “The fear of the LORD is the beginning of wisdom, and knowledge of the Holy One is understanding.” Basically, this verse teaches that the fear of God is foundational to true wisdom; all other types of learning are worthless unless built upon a knowledge of the Lord Himself. Many other passages talk about the fear of the Lord (e.g., Psalm 111:10; Proverbs 1:7; 14:27; 15:33). Before we can understand how the fear of the Lord leads to wisdom, we need to define what the Bible means by “fear” in this context.
In the Bible, the word translated “fear” can mean several things. It can refer to the terror one feels in a frightening situation (Deuteronomy 2:25). It can mean “respect” in the way a servant fears his master and serves him faithfully (Joshua 24:14). Fear can also denote the reverence or awe a person feels in the presence of greatness (Isaiah 6:5). The fear of the Lord is a combination of all of these.
