Hi. Actually YHWH Elohiym used the enemies of the Hebrew Israelites to punish them.
In fact ,something similar is shown in Revelation:
Reve 17:16 and the ten horns that thou didst see upon the beast, these shall hate the harlot, and shall make her desolate and naked, and shall eat her flesh, and shall burn her in fire, 17 for God did give into their hearts to do its mind, and to make one mind, and to give their kingdom to the beast till the sayings of God may be complete,
Yes that is true...
But the Assyrians conquered other cities/towns too.
They were known as the greatest army of their time.
Now that didnt occur just because they took down the Isreali's to punish them.
The Isreali's were just another conquest to them, and yet they did what the Isreali's did and destroyed towns and killed all.
WE know that wasnt the case for the Isreali's... as per the fact they could write about them. Nevertheless, God only allowed punishment not annihilation.
HOWEVER; I agree with you, as per my previous post where I mentioned their humility and being humbled.
Such as those times the other times armies won, yet never destroyed them.
That shows that God led the way of a certain amount of protection to continue the promised line and life of the Messiah, Himself.
BUT also, as I said the Assyrians did not win because they were commanded by God...
They did not believe in God.
I would love to have all the inside scoop on the entirety of the wars back then. But we have only the history of the Bible. Good as it is, it is not quite as explicit as it could be.
AND archeology has uncovered the truths of the OT..
Another thing God has allowed man to discover.
As for Revelation, that clearly shows us that God allows man free will and all creatures free will....and allows the hearts of men to conquer and make war.
God does not use us as pawns, but when war is necessary, it is necessary.
I believe the ancients said 'God commanded them to kill...' actually means they HAD to kill or be killed.
OR it was necessary and they could not change the fate of war.
