Isaiah 10:12

“Wherefore it shall come to pass, &c.] It shall surely be; what God has purposed in his heart, and published in his word, shall certainly be fulfilled: [that] when the Lord hath performed his whole work upon Mount Zion, and on Jerusalem; in correcting, chastising, and humbling the inhabitants thereof, by suffering them to be besieged by the Assyrian army. God sometimes makes use of wicked men to chastise his people; this is his work, and not theirs; and when he begins, he goes on, and finishes it; and when he has done, punishes the instruments he uses; after he has scourged his children, he takes the rod, and breaks it to pieces. I will punish the fruit of the stout heart of the king of…”

“whole work--His entire plan is regard to the punishment of the Jews (Isa 10:5-7). Zion--the royal residence, the court, princes and nobles; as distinguished from "Jerusalem," the people in general. fruit--the result of, that is, the plants emanating from. stout--Hebrew, "greatness of," that is, pride of. glory--haughtiness.”

“Wherefore ... - In this verse God, by the prophet, threatens punishment to the king of Assyria for his pride, and wicked designs. His whole work - His entire plan in regard to the punishment of the Jews. He sent the king of Assyria for a specific purpose to execute his justice on the people of Jerusalem. That plan he would execute entirely by the hand of Sennacherib, and would “then” inflict deserved, punishment on Sennacherib himself, for his wicked purposes. Upon mount Zion - Mount Zion was a part of Jerusalem (see the note at Isaiah 1:8), but it was the residence of the court, the dwelling-place of David and his successors; and perhaps here, where it is mentioned as distinct from…”

“Wherefore - Because of this impudent blasphemy. His work - Of chastising his people so long as he sees fit. Looks - His insolent words and carriage. Isaiah 10:13”

“10:12 Any royal power that exalts itself against the Lord, the Great King, is proud and arrogant (see 2:11-12) and will be crushed.”

“when the Lord: Isa 10:5, Isa 10:6, Isa 14:24-27, Isa 27:9, Isa 46:10, Isa 46:11; Psa 76:10; Pe1 4:17 I will: Isa 10:16-19, Isa 10:25-34, Isa 17:12-14, Isa 29:7, Isa 29:8, Isa 30:30-33, Isa 31:5-9, Isa 37:36-38, Isa 50:11; Jer 50:18 punish the fruit of the stout heart: Heb. visit upon the fruit of the greatness of the heart, Isa 9:9; Job 40:11, Job 40:12; Psa 21:10; Mat 12:33, Mat 15:19 the glory: Isa 2:11, Isa 5:15; Psa 18:27; Pro 30:13; Eze 31:10, Eze 31:14; Dan 4:37 Isaiah 10:13”

“And when He had made use of him as He would, He would throw him away. "And it will come to pass, when the Lord shall have brought to an end all His work upon Mount Zion and upon Jerusalem, I will come to punish over the fruit of the pride of heart of the king of Asshur, and over the haughty look of his eyes." The "fruit" (peri) of the heart's pride of Asshur is his vainglorious blasphemy of Jehovah, in which his whole nature is comprehended, as the inward nature of the tree is in the fruit which hangs above in the midst of the branches; tiph'ereth, as in Zac 12:7, the self-glorification which expresses itself in the lofty look of the eyes. Several constructives are here intentionally grouped…”
