“Therefore will I also deal in fury. My eye will not spare, nor will I have pity. And though they cry in my ears with a loud voice, yet I will not hear them.”
The chapter finishes with Yahweh's again repeated statement that whatever they now do it will be too late. Because of their behaviour His great anger is directed towards them. There will be no mercy and no pity. It is too late for that. Even though they plead with Him in a loud voice, He will not hear. The end is inevitable.
The whole passage reminds us that there is another time coming when God will call ‘the end'. Then too, at the second coming of Jesus Christ, it will be too late to cry for mercy. There will only be judgment to come. And it will be as inexorable as at this time in Jerusalem. Thus we need to be ready.
