Yesterday we read שיר השירים. This is one of the most controversial books in all of Tanach. It was not certain if it should even become one of the books of Tanach, if not for Rabbi Akiva.
He said that if all the other books of Tanach are holy, then שיר השירים is Holy of Holies.
There is a hidden plot to this book that is also meant to answer the scoffers of Judaism. The reuniting of the two lovers at the end of שיר השירים, is a hint to the ultimate reuniting of עם ישראל with Hashem.
After suffering scorn and embarrassment by all those around them, the two lovers prove that only their love is true. Everyone acknowledges this to be true, just as all of the world will one day acknowledge the truth of Judaism.
Again, all of the gloating of the nations of the world and how we were abandoned, will be proven wrong. This is the message of שיר השירים.
