Passage
Therefore sayth the Lord God of hostes, the mightie one of Israel, Ah, I will ease me of mine aduersaries, and auenge me of mine enemies.
Therefore sayth the Lord God of hostes, the mightie one of Israel, Ah, I will ease me of mine aduersaries, and auenge me of mine enemies.
Isaiah 1:22 Thy siluer is become drosse: thy wine is mixt with water.
Isaiah 1:23 Thy Princes are rebellious and companions of theeues: euery one loueth giftes, and followeth after rewards: they iudge not the fatherlesse, neither doeth the widowes cause come before them.
Isaiah 1:24 Therefore sayth the Lord God of hostes, the mightie one of Israel, Ah, I will ease me of mine aduersaries, and auenge me of mine enemies.
Isaiah 1:25 Then I will turne mine hand vpon thee, and burne out thy drosse, till it be pure, and take away all thy tinne.
Isaiah 1:26 And I will restore thy iudges as at the first, and thy counsellers as at the beginning: afterward shalt thou be called a citie of righteousnes, and a faithfull citie.
The verse centers on "therefore", "sayth", "lord", "hostes", "mightie", "israel", "ease", and "mine". It is saying that the verse draws attention to "therefore" and "sayth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 23's "Thy Princes are rebellious and companions of..." into verse 25's "Then I will turne mine hand vpon...", so "therefore" and "sayth" 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 "therefore" and "sayth" with trust shaped by these words, not by a vague optimism outside the passage.
