Matthew Poole and continuators on Psalms 133:2

2 It is like the precious ointment upon the head, that ran down upon the beard, even Aarons beard , that went down to the skirts of his garments.

It is no less grateful and refreshing than that oyl which was plentifully poured forth upon Aarons head at the time of his Consecration to the Priestly Office, which was exceeding pleasant, not onely for the extraordinary fragrancy of it, but because by this, together with the other Rites prescribed, he was initiated into that sacred Office, which was so acceptable to God, and so comfortable and beneficial to the people, as being the happy instrument of making atonement to God for them, and of procuring and maintaining their peace with God, upon which all their happiness of this life and of the next depends.

Or, skirt, for the Hebrew word is of the Singular number. Not to the lower skirt or bottom of his Sacerdotal garment, for that the sacred Oyl was poured forth in so great plenty is not probable, nor was it necessary or convenient; but to the upper skirt of it, or the mouth of it, as this Hebrew word properly signifies, or to the coll[illegible: 1+ letters]r of his upper Priestly garment, which the oyntment falling upon his beard, might easily reach.
