When does Fear of the Lord first appear?

The phrase "fear of the Lord" first appears in The Bible in Exodus 1:17, where the Hebrew midwives are described as fearing God and refusing to follow Pharaoh's orders to kill Hebrew baby boys. This concept is further emphasized throughout the Old Testament, particularly in Proverbs, where it is often associated with wisdom and reverence for God. The "fear of the Lord" signifies a deep respect and awe for God's power and authority.
