This chapter has a lot of imagery! My favorite is in verse 5 "The Lord hath broken the staff of the wicked, the scepters of the rulers."
Then it goes on to talk about Satan, and how he will be "cut down to the ground" or cast out of Heaven... and I like verse 16 "They that see thee shall narrowly look upon thee, and shall say: Is this the man that made the earth to tremble, that did shake kingdoms?".
This section about Satan made me think about how the wicked, or those who have chosen to "follow" Satan will be turned on. Satan doesn't care about those who follow him, and will just as soon destroy them. He is the ultimate liar and master of deceit. It's not like people expect to have their souls destroyed when they make bad decisions with eternal consequences - but in essence, that's how it goes. I think if we thought about it like that, we would do a lot of things differently.
