Passage
For I, Jehovah thy God, Am strengthening thy right hand, He who is saying to thee, `Fear not, I have helped thee.'
For I, Jehovah thy God, Am strengthening thy right hand, He who is saying to thee, `Fear not, I have helped thee.'
Isaiah 41:11 Lo, all those displeased with thee, They are ashamed and blush, They are as nothing, yea, perish Do the men who strive with thee.
Isaiah 41:12 Thou seekest them, and findest them not, The men who debate with thee, They are as nothing, yea, as nothing, The men who war with thee.
Isaiah 41:13 For I, Jehovah thy God, Am strengthening thy right hand, He who is saying to thee, `Fear not, I have helped thee.'
Isaiah 41:14 Fear not, O worm Jacob, ye men of Israel, I helped thee, an affirmation of Jehovah, Even thy redeemer, the Holy One of Israel.
Isaiah 41:15 Lo, I have set thee for a new sharp threshing instrument, Possessing teeth, thou threshest mountains, And beatest small, and hills as chaff thou makest.
The verse centers on "jehovah", "strengthening", "right", "hand", "saying", "thee", "fear", and "helped". It is saying that the verse draws attention to "jehovah" and "strengthening", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 12's "Thou seekest them and findest them not..." into verse 14's "Fear not O worm Jacob ye men...", so "jehovah" and "strengthening" 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 "jehovah" and "strengthening" with trust shaped by these words, not by a vague optimism outside the passage.
