It is like the precious ointment, &c. It is no less grateful and refreshing than that holy anointing oil, which was strongly perfumed, and diffused its fragrance all around, to the great delight of all present, when it was poured upon the head of Aaron, at the time of his consecration to the priestly office, so plentifully, that it ran down his face, even to the collar or binding of his garment. “This verse is explained by Exodus 13:23, &c., where God gave directions concerning the ointment which was to anoint Aaron and his sons. It was to be composed of several rich spices, which, by being rightly tempered and mixed together, yielded a most fragrant odour, and thus became a most expressive emblem of unanimity and concord, in a well-cemented society; all jointly conspiring and contributing, according to their various capacities, tempers, and conditions, to the good of the whole.” Dodd. Dr. Hammond carries this comparison further, and supposes that this anointing oil, being said to go down to the skirts of Aaron's garments, implies that unity is a blessing to the subject, as well as to the governor; to the meanest person in the society, as well as the greatest; which is an undoubted truth, though, perhaps, it might not be intended here by the psalmist.
