Passage
Fear not, thou worm Jacob, and ye men of Israel; I will help thee, saith Jehovah, and thy Redeemer is the Holy One of Israel.
Fear not, thou worm Jacob, and ye men of Israel; I will help thee, saith Jehovah, and thy Redeemer is the Holy One of Israel.
Isaiah 41:12 Thou shalt seek them, and shalt not find them, even them that contend with thee: they that war against thee shall be as nothing, and as a thing of nought.
Isaiah 41:13 For I, Jehovah thy God, will hold thy right hand, saying unto thee, Fear not; I will help thee.
Isaiah 41:14 Fear not, thou worm Jacob, and ye men of Israel; I will help thee, saith Jehovah, and thy Redeemer is the Holy One of Israel.
Isaiah 41:15 Behold, I have made thee [to be] a new sharp threshing instrument having teeth; thou shalt thresh the mountains, and beat them small, and shalt make the hills as chaff.
Isaiah 41:16 Thou shalt winnow them, and the wind shall carry them away, and the whirlwind shall scatter them; and thou shalt rejoice in Jehovah, thou shalt glory in the Holy One of Israel.
The verse centers on "fear", "thou", "worm", "jacob", "israel", "help", "thee", and "saith". It is saying that the verse draws attention to "fear" and "thou", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "For I Jehovah thy God will hold..." into verse 15's "Behold I have made thee to be...", so "fear" and "thou" 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 "thou" with trust shaped by these words, not by a vague optimism outside the passage.
