The phrase "Whom shall I fear?" is a well-known line from the Bible, specifically from Psalm 27:1. The full verse in the King James Version (KJV) reads:

Psalm 27:1
The Lord is my light and my salvation; whom shall I fear? The Lord is the strength of my life; of whom shall I be afraid?

This verse expresses trust and confidence in God's protection, implying that with God on one's side, there is no need to fear anyone or anything. If you'd like, I can provide this verse in other translations or offer more context and commentary!
