To threaten Israel and the Jewish people is to actually threaten God. Assyria learned this lesson when God answered King Hezekiah prayers for help.
2 Kings 19:20-28
Then Isaiah the son of Amoz sent to Hezekiah, saying, “Thus says the Lord God of Israel: ‘Because you have prayed to Me against Sennacherib king of Assyria, I have heard.’ This is the word which the Lord has spoken concerning him:
‘The virgin, the daughter of Zion,
Has despised you, laughed you to scorn;
The daughter of Jerusalem
Has shaken her head behind your back!
‘Whom have you reproached and blasphemed?
Against whom have you raised your voice,
And lifted up your eyes on high?
Against the Holy One of Israel.
By your messengers you have reproached the Lord,
And said: “By the multitude of my chariots
I have come up to the height of the mountains,
To the limits of Lebanon;
I will cut down its tall cedars
And its choice cypress trees;
I will enter the extremity of its borders,
To its fruitful forest.
I have dug and drunk strange water,
And with the soles of my feet I have dried up
All the brooks of defense.”
‘Did you not hear long ago
How I made it,
From ancient times that I formed it?
Now I have brought it to pass,
That you should be
For crushing fortified cities into heaps of ruins.
Therefore their inhabitants had little power;
They were dismayed and confounded;
They were as the grass of the field
And the green herb,
As the grass on the housetops
And grain blighted before it is grown.
‘But I know your dwelling place,
Your going out and your coming in,
And your rage against Me.
Because your rage against Me and your tumult
Have come up to My ears,
Therefore I will put My hook in your nose
And My bridle in your lips,
And I will turn you back
By the way which you came.
PRAY YOUR NATION NEVER TURNS AGAINST GOD BY TURNING AGAINST ISRAEL.
