Isaiah speaks with authority about Babylon’s fate at the hands of the Medes (Isaiah 13:17-20). If you recall, Isaiah began his book speaking about events that transpire in 740 B.C. Some modern scholars have argued that Isaiah could not have written all of this book because the destruction of the Babylonians foretold in today’s reading happened two centuries later, around 539 B.C. This of course assumes that Isaiah did not actually prophesy events based on the revelation of an all-knowing God. In other words, to those who believe that miracles such as accurate prophecies about the future cannot happen, Isaiah couldn’t have actually written these details about Babylon’s demise.
As believers, part of embracing the trustworthiness of scripture means we embrace the trustworthiness of the authors of the particular books. Isaiah claimed to write the entire book, and the New Testament authors treat Isaiah as the author as well. This is important to remember.
One last note: the word “Lucifer” is used to describe Babylon in a way that many have interpreted to also reflect Satan’s fall from heaven. A straightforward reading of this passage could simply reflect Babylon’s pride and destruction. However, it would be very much in line with the rest of scripture for Babylon to also refer to the reign of Satan.
