In what manner? Thru the 70? What are you referring to?
Lets look at that one again.
Isaiah 10:O Assyrian, the rod of mine anger, and the staff in their hand is mine indignation 6 I will send him against an hypocritical nation,
(ancient Israel) and against the people of my wrath will I give him a charge, to take the spoil, and to take the prey, and to tread them down like the mire of the streets.7 Howbeit he meaneth not so, neither doth his heart think so; but it is in his heart to destroy and cut off nations not a few.....
Then he spends multi verses denouncing Assyria's pride and intentions and then God makes this statement to them. 15 Shall the axe boast itself against him that heweth therewith? or shall the saw magnify itself against him that shaketh it?
as if the rod should shake itself against them that lift it up, or as if the staff should lift up itself, as if it were no wood.
All of this meaning. The rod God rules the nations with in this case is the nation of Assyria.
Here the rod God wields to purge Israel of idolaters is the nations that ruled over them.
Ezekiel 20: 32 And that which comes into your mind shall not be at all, that ye say, We will be as the heathen, as the families of the countries, to serve wood and stone. 33 As I live, saith the Lord GOD, surely with a mighty hand, and with a stretched out arm, and with fury poured out, will I rule over you: 34 And I will bring you out from the people, and will gather you out of the countries wherein ye are scattered, with a mighty hand, and with a stretched out arm, and with fury poured out. 35 And I will bring you into the wilderness of the people, and there will I plead with you face to face. 36 Like as I pleaded with your fathers in the wilderness of the land of Egypt, so will I plead with you, saith the Lord GOD.
37 And I will cause you to pass under the rod, and I will bring you into the bond of the covenant: 38 And I will purge out from among you the rebels, and them that transgress against me: I will bring them forth out of the country where they sojourn, and they shall not enter into the land of Israel: and ye shall know that I am the LORD.
Here Israel is the rod of God's inheritance.
Jeremiah 10: 16 The portion of Jacob is not like them: for he is the former of all things;
and Israel is the rod of his inheritance: The LORD of hosts is his name.
Here God rules the nations with the rod of the mouth of the messiah which is symbolic of his word. Same thing in Revelation the sword of the his mouth is his word. Beside Jesus himself being the rod of God in verse 1.
Isaiah 11:1 And there shall come forth a rod out of the stem of Jesse, and a Branch shall grow out of his roots: 2 And the spirit of the LORD shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the LORD;3 And shall make him of quick understanding in the fear of the LORD: and he shall not judge after the sight of his eyes, neither reprove after the hearing of his ears: 4 But with righteousness shall he judge the poor, and reprove with equity for the meek of the earth:
and he shall smite the earth with the rod of his mouth, and with the breath of his lips shall he slay the wicked.5 And righteousness shall be the girdle of his loins, and faithfulness the girdle of his reins.
These animals represent the nations of the world lying down at peace with one another. Not seeking to conquer, plunder and enslave their neighbors because of the influence of Gods invisible kingdom. 6 The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them. 7 And the cow and the bear shall feed; their young ones shall lie down together: and the lion shall eat straw like the ox. 8 And the sucking child shall play on the hole of the asp, and the weaned child shall put his hand on the cockatrice' den.9 They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the LORD, as the waters cover the sea.
This are just some of the examples of the way in which Jesus rules the world with a rod of iron. Or how about these precious promises and prophecies that pertain to this age in nations that meet the conditions due to the influnce of Christians and the Bible in their nation. Notice none of these promises speak of a utopian world but a world where the righteous are winning the battles against the wicked. Something non existent in the ancient world outside ancient Israel.
Isaiah 54:14 In righteousness shall you be established: you shall be far from oppression; for you shall not fear: and from terror; for it shall not come near you. 15 Behold, they shall surely gather together, but not by me: whoever shall gather together against you shall fall for your sake.....17 No weapon that is formed against you shall prosper; and every tongue that shall rise against you in judgment you shall condemn.
Isaiah 60:26 And they shall bring the glory and honor of the nations into it 12 For the nation and kingdom that will not serve you shall perish; yes, those nations shall be utterly wasted.
Zechariah 13:8 In that day shall the LORD defend the inhabitants of Jerusalem; and he that is feeble among them at that day shall be as David; and the house of David shall be as God, as the angel of the LORD before them.
Psalm: 149:7 To execute vengeance upon the heathen, and punishments upon the people; 8 To bind their kings with chains, and their nobles with fetters of iron; 9 To execute upon them the judgment written: this honors have all his saints. Praise ye the LORD.
Daniel 7:27. And the kingdom and empire, and the greatness of the dominion under the whole heaven, will be given to the people of the saints of the most High, whose kingdom is an everlasting kingdom, and all empires shall serve and obey him.
Revelation 20:8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog and Magog, to gather them together to battle: the number of whom is as the sand of the sea. 9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
