For I the LORD your God will hold your right hand, saying unto you, Fear not; I will help you.
Read Chapter 41
Cyril of Alexandria
There are many who think of the holy mysteries and the saving message in disrespectful ways, but they amount to nothing, and such impious adversaries will perish. For those who oppose the divine agents of preaching are doing no less than fighting against the teachings of godliness.… For thousands will make war against God’s ministers, but these will end up as though they never existed and will clearly be brought low, falling under the machinery of the wrath of God. [Isaiah] tells them to quit relying on human strength and their own foolhardiness, saying, “I am your God who strengthens your arm,” that is, I am the one who supports you and makes you prevail in any test. I say to you, “Do not be afraid, O little Israel.” - "Commentary on Isaiah 220.127.116.11–14"
