Isaiah's Writing Style: Groups of Words

The prophet will use a theme in a group of verses, and use words from that theme. Then, in a few verses later, he will use a completely different one. Once you notice the similarities between them, you can see the groups.

I think he uses these to show, in contrast, how the people or the situation is.

There are also arching summaries as well, across the groups of verses:
