Isaiah 37

In this chapter the text continues with the narrative about Sennacherib's threats against Jerusalem and mocking of the God of Israel.  Then in verse 22 he returns to poetry and God poetically declares his plans for the arrogant king of Assyria. I wonder if Isaiah sang these words from God? If God planted a catchy tune along with the words in Isaiah's mind? I can picture the prophet singing out a lymric belitteling the invading king. But I also wonder if the tune was so attractive that the song was heard in the camp of the Assyrian army and was even noticed by the king. "What a lovely little Hebrew tune." The king might have spoken off-hand. "I wonder what it means?"  The song woulf have become a haunt in his mind as he marched his army back home still stinging from the unexplained deaths of 185,000 healthy warriors.
It took me about 6 minutes to read this chapter.
