When the non-Jews entered to destroy the Beis Hamikdosh, they found two Keruvim intertwined in an intimate embrace, like the deep love between husband and wife.
(Since the Aron had already been hidden, these were other decorative Keruvim and not the Keruvim from the Aron cover).
The Temple was being destroyed and the Jewish people sent into exile because of their terrible sins. How could it be that at this time the Keruvim were in the most intimate of positions?
There is a halacha which obligates a man to spend intimate time with wife before leaving on a journey. It is a time of heightened love and closeness.
Despite the fact that the Jewish people were going into Golus, hidden in the Holy of Holies, Hashem’s deep love for his bride shone deeper than ever. Yes Golus is concealment, but it is the beginning of the process of revealing the greatest of lights.
We have a tradition that on the day of Tisha B’av, at the moment of the Churban itself, the Neshama of Moshiach was born. This Neshama was conceived through the deep spiritual union embodied in those Keruvim.
After conception, hidden inside the womb, the fetus grows and develop, finally emerging to a state of revelation at birth. The conception of Geulah began nearly 2000 years ago in the privacy of the Holy of Holies. Ever since, it has been developing and growing. It is now long overdue and ready to emerge.
