KJV:
Fear thou not; for I am with thee: be not dismayed; for I am thy God: I will strengthen thee; yea, I will help thee; yea, I will uphold thee with the right hand of my righteousness.
NKJV:
Fear not, for I am with you; be not dismayed, for I am your God. I will strengthen you, yes, I will help you, I will uphold you with My righteous right hand.
NIV:
So do not fear, for I am with you; do not be dismayed, for I am your God. I will strengthen you and help you; I will uphold you with my righteous right hand.
Interpretation:
God commands His people not to fear harmful things because He is present with them. His presence provides the reason for courage. He promises to strengthen, help, and uphold those who trust Him. The verse distinguishes between unhealthy fear of circumstances and healthy fear of God.
