Yahweh seems to be mad at the leaders of Judah who are attempting to plot with Assyria. They have a hidden dark plan since they seem to say that no one sees them or knows about it. They have things upside down because they are the creatures, not the creators. They are the clay that thinks that they are the potters who mold the clay. They were made by the Creator God as in Genesis, chapter 2. They were the formed, not the formers. Why are they saying that the Creator God does not understand, since they are mere clay?
Now Isaiah takes on the immoral people who call evil good and the reverse, good evil. They put darkness on light and light on darkness. They say something is bitter when it is sweet, and vice versa. They live in an immoral upside down world.
