I didn't recognize the verse at first until I looked it up in the KJV. I've long grown accustomed to the language of the KJV.
Proverbs 22:4 (KJV)
By humility and the fear of the LORD are riches, and honour, and life.
The fear of the Lord is and important concept that is well worth taking the time to study. Sometimes that fear was actual fear, but generally it does speak more to proper reverence or respect. I found 30 occurrences of this term in the KJV. Primarily found in Proverbs and Isaiah with only one occurrence in the New Testament (Acts 9:31).
Proverbs 1:7 tells us that the fear of the Lord is the beginning of understanding and the concept is important enough that this is repeated in Job 28:28, Ps 111:10. Having a proper reverence or respect for God will lead us to understanding his words and his way.
God's way is blessed in so many ways. Most of the blessings are spiritual when we fear the Lord. Sometimes God blesses us in material ways as well, but God knows when the material might bring harm rather than good.
