Ezekiel 7 – What does “their arrogance has blossomed” mean? 2019

Ezek 7:11
'Violence has grown into a rod of wickedness. None of them shall remain, none of their multitude, none of their wealth, nor anything eminent among them.

Elohim says that their arrogance has blossomed. He is speaking of a complete destruction.
There is a famous poem that ends with a line that says, "There is no joy in Mudville..." That's the case with Judah, only the situation is much more dire than the Mighty Casey striking out. Those in Judah were either already killed, held captive by Babylon, or soon to be either.

Elohim is going to make all of those in Judah equal to one another. There will no more be the rich and the poor, the strong and the weak. There will only be the dead and the destitute.

Let us heed the warnings of the prophets!
