Passage
Ye <FI>are<Fi> My witnesses, an affirmation of Jehovah, And My servant whom I have chosen, So that ye know and give credence to Me, And understand that I <FI>am<Fi> He, Before Me there was no God formed, And after Me there is none.
Ye <FI>are<Fi> My witnesses, an affirmation of Jehovah, And My servant whom I have chosen, So that ye know and give credence to Me, And understand that I <FI>am<Fi> He, Before Me there was no God formed, And after Me there is none.
Isaiah 43:8 He brought out a blind people who have eyes, And deaf ones who have ears.
Isaiah 43:9 All the nations have been gathered together, And the peoples are assembled, Who among them declareth this, And former things causeth us to hear? They give their witnesses, And they are declared righteous, And they hear and say, `Truth.'
Isaiah 43:10 Ye <FI>are<Fi> My witnesses, an affirmation of Jehovah, And My servant whom I have chosen, So that ye know and give credence to Me, And understand that I <FI>am<Fi> He, Before Me there was no God formed, And after Me there is none.
Isaiah 43:11 I--I <FI>am<Fi> Jehovah, And besides Me there is no saviour.
Isaiah 43:12 I--I declared, and saved, and proclaimed, And there is no stranger with you, And ye <FI>are<Fi> My witnesses, an affirmation of Jehovah, And I <FI>am<Fi> God.
The verse centers on "witnesses", "affirmation", "jehovah", "servant", "chosen", "give", "credence", and "understand". It is saying that the verse draws attention to "witnesses" and "affirmation", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "All the nations have been gathered together..." into verse 11's "I--I FI am Fi Jehovah And besides...", so "witnesses" and "affirmation" 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 "witnesses" and "affirmation" with trust shaped by these words, not by a vague optimism outside the passage.
