Tehillim 133:2-3

Orthodox Jewish Bible

² It is like the precious shemen upon the rosh, that ran down upon the beard, even Aharon’s beard; that went down to the collar of his robes;

³ As the tal of Chermon, and as the dew that descended upon the mountains of Tziyon; for there Hashem commanded the brocha, even Chayyim Ad Olam.
