Passage
Fear not, for I am with thee: turn not aside, for I am thy God: I have strengthened thee, and have helped thee, and the right hand of my just one hath upheld thee.
Fear not, for I am with thee: turn not aside, for I am thy God: I have strengthened thee, and have helped thee, and the right hand of my just one hath upheld thee.
Isaiah 41:8 But thou Israel, art my servant, Jacob whom I have chosen, the seed of Abraham my friend:
Isaiah 41:9 In whom I have taken thee from the ends of the earth, and from the remote parts thereof have called thee, and said to thee: Thou art my servant, I have chosen thee, and have not cast thee away.
Isaiah 41:10 Fear not, for I am with thee: turn not aside, for I am thy God: I have strengthened thee, and have helped thee, and the right hand of my just one hath upheld thee.
Isaiah 41:11 Behold all that fight against thee shall be confounded and ashamed, they shall be as nothing, and the men shall perish that strive against thee.
Isaiah 41:12 Thou shalt seek them, and shalt not find the men that resist thee: they shall be as nothing: and as a thing consumed the men that war against thee.
The verse centers on "fear", "thee", "turn", "aside", "strengthened", and "helped". 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 "In whom I have taken thee from..." into verse 11's "Behold all that fight against thee shall...", 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.
