Passage
Thy first father sinned, And thine interpreters transgressed against me,
Thy first father sinned, And thine interpreters transgressed against me,
Isaiah 43:25 I--I <FI>am<Fi> He who is blotting out Thy transgressions for Mine own sake, And thy sins I do not remember.
Isaiah 43:26 Cause me to remember--we are judged together, Declare thou that thou mayest be justified.
Isaiah 43:27 Thy first father sinned, And thine interpreters transgressed against me,
Isaiah 43:28 And I pollute princes of the sanctuary, And I give Jacob to destruction, and Israel to revilings!
The verse centers on "first", "father", "sinned", "thine", "interpreters", "transgressed", and "against". It is saying that the verse draws attention to "first" and "father", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 26's "Cause me to remember--we are judged together..." into verse 28's "And I pollute princes of the sanctuary...", so "first" and "father" 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 "first" and "father" with trust shaped by these words, not by a vague optimism outside the passage.
