For all this his anger is not turned away, but his hand is stretched out still. Even in the midst of the most extreme graphic warnings, a brief reminder that God’s hand of mercy is still outstretched shows us that His first desire is always to spare His people. The phrase is repeated four more times in Isaiah,

Thank God for His mercy. but the attempt to use "but his hand is stretched out still" as "a brief reminder that God’s hand of mercy is still outstretched" is erroneous. For the contextual meaning is that despite the judgments that have already come, the Lord's hand is still stretched out in judgments, which is why they are consequently described.

The word for "but" is not in the Hebrew, and that the Lord's hand is still stretched out only has to do with more judgment.

Keil & Delitzsch Commentary on the Old Testament acknowledge this also on Is. 5:25: This judgment, which was closer at hand, would consist in the fact that Jehovah would stretch out His hand in His wrath over His people (or, as it is expressed elsewhere, would swing His hand... But “for all this” (Beth, = “notwithstanding,” “in spite of,” as in Job_1:22) the wrath of Jehovah, as the prophet foresaw, would not turn away, as it was accustomed to do when He was satisfied; and His hand would still remain stretched out over Judah, ready to strike again.

Likewise Barnes:

For all this - Notwithstanding all this calamity, his judgments are not at an end. He will punish the nation more severely still. In what way he would do it, the prophet proceeds in the remainder of the chapter to specify;

Also Jamieson, Fausset and Brown:

For all this, etc. — This burden of the prophet’s strains, with dirge-like monotony, is repeated at Isa_9:12, Isa_9:17, Isa_9:21; Isa_10:4. With all the past calamities, still heavier judgments are impending; which he specifies in the rest of the chapter (Lev_26:14, etc.).

And Gill:

but his hand is stretched out still; to inflict yet sorer judgments. The Targum is "by all this they turn not from their sins, that his fury may turn from them; but their rebellion grows stronger, and his stroke is again to take vengeance on them;'' which expresses their impenitence and hardness of heart, under the judgments of God, which caused him to take more severe methods with them.
