Passage
And I will turn my hand upon thee, and will thoroughly purge away thy dross, and take away all thine alloy;
And I will turn my hand upon thee, and will thoroughly purge away thy dross, and take away all thine alloy;
Isaiah 1:23 thy princes are rebellious, and companions of thieves; every one loveth presents, and hunteth after rewards; they judge not the fatherless, and the cause of the widow cometh not unto them.
Isaiah 1:24 Therefore saith the Lord, Jehovah of hosts, the Mighty One of Israel: Ah! I will ease me of mine adversaries, and avenge me of mine enemies.
Isaiah 1:25 And I will turn my hand upon thee, and will thoroughly purge away thy dross, and take away all thine alloy;
Isaiah 1:26 and I will restore thy judges as at the first, and thy counsellors as at the beginning. Afterwards thou shalt be called, Town of righteousness, Faithful city.
Isaiah 1:27 Zion shall be redeemed with judgment, and they that return of her with righteousness.
The verse centers on "turn", "hand", "upon", "thee", "thoroughly", "purge", "away", and "dross". It is saying that the verse draws attention to "turn" and "hand", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 24's "Therefore saith the Lord Jehovah of hosts..." into verse 26's "and I will restore thy judges as...", so "turn" and "hand" 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 "turn" and "hand" with trust shaped by these words, not by a vague optimism outside the passage.
