Isaiah 10:5

“O Assyrian, the rod of mine anger, &c.]. Either as calling him to come against the land of Israel to spoil it, so Kimchi; or as grieving that he was obliged to make use of him in such a manner against his people; or as threatening him with ruin. So the Targum, Septuagint, and all the Oriental versions render it, “woe to the Assyrian”; wherefore this, and what follows, serve to comfort the people of God; that though they should be carried captive by the Assyrians, yet they should be utterly destroyed, and a remnant of the Jews should be saved. The Assyrian monarch is called the “rod of God’s anger”, because he was made use of by him as an instrument to chastise and correct Israel for their…”

“It was written when Assyria proposed (a design which it soon after tried to carry out under Sennacherib) to destroy Judah and Jerusalem, as it had destroyed Samaria. This is the first part of Isaiah's prophecies under Hezekiah. Probably between 722 and 715 B.C. (see Isa 10:27). (Isa 10:9, Isa 10:11 show that Samaria was destroyed before this prophecy) O Assyrian, &c.--rather, "What, ho (but MAURER, Woe to the) Assyrian! He is the rod and staff of Mine anger (My instrument in punishing, Jer 51:20; Psa 17:13). In their hands is Mine indignation" [HORSLEY, after JEROME]. I have put into the Assyrians' hands the execution of Mine indignation against My people.”

“O Assyrian - The word הוי hôy, is commonly used to denounce wrath, or to indicate approaching calamity; as an interjection of threatening; Isaiah 1:4. ‘Wo sinful nation;’ Isaiah 10:8, Isaiah 10:11, Isaiah 10:18, Isaiah 10:20-21; Jeremiah 48:1; Ezekiel 13:2. The Vulgate so understands it here: Vae Assur; and the Septuagint, Οὐαι Ἀσσυρίοις Ouai Assuriois - ‘Woe to the Assyrians.’ So the Chaldee and the Syriac. It is not then a simple address to the Assyrian; but a form denouncing wrath on the invader. Yet it was not so much designed to intimidate and appal the Assyrian himself as to comfort the Jews with the assurance that calamity should overtake him. The ‘Assyrian’ referred to here was…”

“O Assyrian - This is God's invitation to him to take the charge, and set upon the work. The rod - The instrument of mine anger, wherewith I shall chastise my people. Anger - Mine anger against my people puts the weapons of war into their hand. Isaiah 10:6”

“10:5–11:16 The primacy of the Lord’s moral law was established in 9:8–10:4; this passage works out the implications of the law: (1) Assyria was only a tool in God’s hands and was therefore as liable to judgment by God as any other nation (10:5-19, 28-34); (2) those among God’s people who trusted in him and obeyed his covenant would be rescued (10:20-27); and (3) God would establish his kingdom on earth (ch 11). 10:5-19 This judgment was pronounced on Assyria because of their ruthless destruction of nations (10:7), blasphemous boasting (10:12), oppression (10:13-14), and self-perceived autonomy (10:15). 10:5 The Assyrians were God’s instrument (rod . . . club) in judging Syria, Israel, and…”

“O Assyrian: or, Woe to the Assyrian, Heb. O Asshur, Gen 10:11 the rod: Isa 10:15, Isa 8:4, Isa 14:5, Isa 14:6; Psa 17:14, Psa 125:3; Jer 51:20-24 and: or, though Isaiah 10:6”

“The law of contrast prevails in prophecy, as it does also in the history of salvation. When distress is at its height, it is suddenly brought to an end, and changed into relief; and when prophecy has become as black with darkness as in the previous section, it suddenly becomes as bright and cloudless as in that which is opening now. The hoi (woe) pronounced upon Israel becomes a hoi upon Asshur. Proud Asshur, with its confidence in its own strength, after having served for a time as the goad of Jehovah's wrath, now falls a victim to that wrath itself. Its attack upon Jerusalem leads to its own overthrow; and on the ruins of the kingdom of the world there rises up the kingdom of the great and…”
