Literary analysis: The glory:burning mage from he previous verse is now pulled into this verse. The image is reversed to burning:glory (with the glory appearing in the next verse), with the fire being equated with the Lord. The correlation between the light and flame of Israel being the Lord evokes the image of the pillar of fire that lead God's people out of Egypt. This very clearly becomes an image of deliverance, a them that will be picked up in verse 20.
“His Fat Ones”
Literary analysis: As a consequence of the pride of Assyria the Lord will bring destruction upon them. This is presented with two parallel reversals. The first element represents the good that Assyria believes to be due to its own hand, and the second element contrasts that with an opposite that is related to the nature of the first element. Thus:
The fat:lean pair is easy to understand. The fatness of economic prosperity is contrasted with the coming leanness of economic failure. The glory:burning pair contrasts the glory with the destructiveness of fire.
