This is talking about 70 A.D., Jews don't have a root to be Jews anymore.
Mal 4:1
For, behold, the day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble: and the day that cometh shall burn them up, saith the LORD of hosts, that it shall leave them neither root nor branch.
Two Verses before Mal 4:1
Mal 3:17
And they shall be mine, saith the LORD of hosts, in that day when I make up my jewels; and I will spare them, as a man spareth his own son that serveth him.
//Could the people spared be Christians told to flee The City?
Do you think maybe the Gentiles are outside the border? And that all of this already started?:
Mal 1:5
And your eyes shall see, and ye shall say, The LORD will be magnified from the border of Israel.
Mal 1:11
For from the rising of the sun even unto the going down of the same my name shall be great among the Gentiles; and in every place incense shall be offered unto my name, and a pure offering: for my name shall be great among the heathen, saith the LORD of hosts.
Does anyone think "the wrath to come" ...didn't happen yet?
Matthew 3:7,10
But when he saw many of the Pharisees and Sadducees come to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come?
And now also the axe is laid unto the root of the trees: therefore every tree which bringeth not forth good fruit is hewn down, and cast into the fire.
