Psalms 133:2

“[It is] like the precious ointment upon the head, etc.] The composition which Moses was ordered to make of the principal spices, and therefore called precious; and which was poured on the heads of kings and priests, when they were anointed with it, (<023023>Exodus 30:23-25); that ran down upon the beard, [even] Aaron’s beard; this was put upon the head of Aaron when he was anointed, and so on any other high priest, and trickled down to his beard; (see <022907>Exodus 29:7).

Compare the notes at Isaiah 61:3, on the phrase “oil of joy.” Anointing with oil was common on festivals and joyous occasions (see the notes at Psalms 23:5), and hence, it became an emblem of anything joyous, happy, beautiful; and the idea seemed to be carried to the highest degree when it was connected with the anointing of a high priest to the sacred duties of his…”

“Ointment - It is no less grateful and refreshing than that oil which was poured forth upon Aaron's head at the time of his consecration to the priestly office. Skirts - Not to the lower skirt or bottom of his sacerdotal garment, but to the upper skirt of it, or the mouth of it, as the Hebrew word properly signifies. Psalms 133:3”

“133:2 The anointing oil was the oil used to ordain and consecrate Aaron for service in his office (see Exod 29:7). • head . . . beard . . . border of his robe: The oil consecrated Aaron completely.”

“It is like: Psa 141:5; Pro 27:9; Sol 1:3; Joh 12:3 that ran down: Exo 30:25-30; Lev 8:12 Psalms 133:3”
