Parshat Tetzaveh explores the topic of the kohanim. In this parsha Aaron gets anointed with oil, which is similar to Tehillim (Psalm) 133. Tehillim 133 can help us understand how the anointing of a kohen gadol came to be and how we can make that happen in the future. Chapter 133 starts by saying that this is a song by David. It continues to say how great it is for brothers to live and be together. Brothers being one is like the good oil that is poured on Aaron that falls on his beard and garments. The anointing oil being poured on Aaron is like the dew of Chermon falling on the mountain of Zion because Hashem commanded the blessing there forever.

These three comparisons were made to show us a bigger picture. When we are unified, Hashem will bring His presence even closer to us. Only when this happens can we re-anoint a kohen gadol and b’ezrat Hashem herald Mashiach’s arrival. However, the chapter does not end with those two comparisons; it ends with comparing it to the dew of the Chermon mountain falling onto the mountain of Zion. Malbim (a commentator) points out, what does it mean that the dew is falling from the mountain of Chermon to the mountain of Zion? He explains that the dew on Chermon, the tallest mountain in Israel, was put there only for the purpose of falling onto the mountain of Zion. This indicates that Hashem is ready for redemption, but the real question is: are we? The dew and redemption are ready to come down but we need to take the next step in order to achieve it.
