Passage
Fear 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.
Fear 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.
Isaiah 41:8 But thou, Israel, my servant, Jacob, whom I have chosen, the seed of Abraham, my friend
Isaiah 41:9 thou whom I have taken from the ends of the earth, and called from the extremities thereof, and to whom I said, Thou art my servant, I have chosen thee and not rejected thee,
Isaiah 41:10 Fear 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.
Isaiah 41:11 Lo, all that are incensed against thee shall be ashamed and confounded; they that strive with thee shall be as nothing, and shall perish.
Isaiah 41:12 Thou shalt seek them, and shalt not find them them that contend with thee; they that war against thee shall be as nothing, and as a thing of nought.
The verse centers on "fear", "thee", "dismayed", "strengthen", "help", and "uphold". It is saying that the verse draws attention to "fear" and "thee", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "thou whom I have taken from the..." into verse 11's "Lo all that are incensed against thee...", so "fear" and "thee" belong inside that flow. In Isaiah context, the local focus is the Holy One of Israel, judgment and restoration, the servant of the LORD, and Zion's hope.
A plain takeaway is to answer the verse's own emphasis on "fear" and "thee" with trust shaped by these words, not by a vague optimism outside the passage.
