G-d's Wrath Towards the Leaders

The main theme of these Pesukim are anger and destruction. The Mikonein starts off describing all the anger and destruction of G-d. This Perek is mostly the Mikonein talking and we don't hear Yisrael talking until later in the Perek when she comes to defend herself again. G-d's anger is probably the biggest theme in Pesukim 1-19:

1: G-d brought Bat Tzion into darkness with his anger. 

2: He destroyed them in His anger

3: In His anger, He cut down the strength and leaders of Yisrael.

4: He poured out his fury like fire

6: He poured out his fury on the king and priest

These few Pesukim show how angry G-d was. G-d is angry at his leaders. He is destroying the people with all the anger that is built up towards his leaders. His anger is described as fire something extremely destructive and can grow and grow and destroy everything in sight. With his anger he is making a big destruction through the land:

1: He cast down water onto the land

2: Hashem swallowed and didn't pity all the people of Yaakov.

3: He's removing his right hand and it burned in Yaakov a flaming fire that consumed everything

4: He bent like the bow of his enemy. He stood with His right hand stretched. He killed all those peasant to the eye.

5: He swallowed Yisrael and her palace and surroundings. 

7: He delivered the palace into the hands of the enemy. 

8: Hashem determined that He will destroy the walls of Bat Tzion. G-d is measuring a line to destroy. He didn't take bak His hand from swallowing. He destroyed His walls. 

9: Her gates sunk in the land. 

You can see that G-d's anger is strictly directed to his leaders. He is blaming the leaders for the reason of destruction. As the Mikonein describes the destruction he focuses on what is happening to the leaders:

2: He profaned the kingdom and his princes

6: He poured out His fury on the king and the priest

9: Her kings and priest are exiled 

As the whole city is being destroyed, it's the leaders that are being focused on. It is because it's trying to show that it was the leaders who led them astray. The fault is the leaders for causing such a horrible destruction.
