I was aware from one commentary that a different interpretation of “His hand is stretched out still” existed. However, it wasn’t mentioned in every one I consulted so I pressed forward with my point.
All scripture is divinely inspired, but not every commentary is perfect. That doesn’t mean we can’t work harder to fact-check our sources before putting stuff out there first.
The commentaries were superfluous, and only confirm what is obvious, which you turned into making the hand of judgment into an offer of mercy, which simply nowhere contextually seen.
Instead, we have a description of judgments for "He hath stretched forth his hand against them," followed by the warning that there are yet more judgment to come, for "his hand is stretched out still."
Therefore is the anger of the LORD kindled against his people, and he hath stretched forth his hand against them , and hath smitten them: and the hills did tremble, and their carcases were torn in the midst of the streets. For all this his anger is not turned away, but his hand is stretched out still . (Isa 5:25)
Likewise the only description in other verses of His hand stretch out till is that of judgment:
The Syrians before, and the Philistines behind; and they shall devour Israel with open mouth. For all this his anger is not turned away, but his hand is stretched out still. For the people turneth not unto him that smiteth them, neither do they seek the LORD of hosts. Therefore the LORD will cut off from Israel head and tail, branch and rush, in one day. (Isa 9:12-14)
Therefore the Lord shall have no joy in their young men, neither shall have mercy on their fatherless and widows: for every one is an hypocrite and an evildoer, and every mouth speaketh folly. For all this his anger is not turned away, but his hand is stretched out still. For wickedness burneth as the fire: it shall devour the briers and thorns, and shall kindle in the thickets of the forest, and they shall mount up like the lifting up of smoke. (Isa 9:17-18)
Manasseh, Ephraim; and Ephraim, Manasseh: and they together shall be against Judah. For all this his anger is not turned away, but his hand is stretched out still. (Isa 9:21)
Without me they shall bow down under the prisoners, and they shall fall under the slain. For all this his anger is not turned away, but his hand is stretched out still. O Assyrian, the rod of mine anger, and the staff in their hand is mine indignation. (Isa 10:4-5)
That I will break the Assyrian in my land, and upon my mountains tread him under foot: then shall his yoke depart from off them, and his burden depart from off their shoulders. This is the purpose that is purposed upon the whole earth: and this is the hand that is stretched out upon all the nations. For the LORD of hosts hath purposed, and who shall disannul it? and his hand is stretched out, and who shall turn it back? (Isa 14:25-27)
Now the Egyptians are men, and not God; and their horses flesh, and not spirit. When the LORD shall stretch out his hand, both he that helpeth shall fall, and he that is holpen shall fall down, and they all shall fail together. (Isa 31:3)
Likewise if you do a word search of stretch out hand (H3027 H5186) you will abundant other examples of this being in executing judgment.
I appreciate you wanting to show that God can yet offers mercy amid judgment, and thank God there are texts that show this, but "His hand is stretched out still" is not one of them.
