It is very interesting that the Greeks in particular were responsible for the desecration of the Beis Hamikdash.
The word Heichal in gematria = 65, and the yavan = 66. The malchus of Yavan had an extra strength that allowed them to overpower the Heichal.
When they desecrated the Heichal they davka desecrated the oils that were there. Why?
The Maharal answers, that it is because shemen is distinct to kedusha. Raaya ladavar is shemen hamishcha (shmos, 30:26-33) knowing this well they made it their mission to entirely desecrate all kedusha that the beis hamikdash inhibited.
