I’ve often wondered why Christian love and unity was compared with Aaron’s anointing or the dew of Hermon. Here are my insights plus that of the great commentator John Gill.
“Behold, how good and how pleasant it is for brethren to dwell together in unity! It is like the precious ointment upon the head, that ran down upon the beard, even Aaron’s beard: that went down to the skirts of his garments; As the dew of Hermon, and as the dew that descended upon the mountains of Zion: for there the Lord commanded the blessing, even life for evermore.” Psalm 133.
Christian love from our anointing is a public demonstration (John 13:34,35) and personal reassurance of one’s calling (I John 2:27). In Christ we are all anointed as prophets, priests and kings so as to minister to each other. Christian fellowship, like the oil, is precious and refreshing like the dew to invigorate.
“David means the superior aperture of the garment, that which we call the neck or collar band; This anointing oil was typical of the grace of the Spirit, the unction from the Holy One; which has been poured on Christ, the head of the church, without measure; and with which he has been anointed above his fellows; and from him it is communicated to all his members (I John 2:27); to every one of which is given grace, according to the measure of the gift of Christ; and who from his fullness receive, and grace for grace: and particularly brotherly love is compared to this ointment; because of the preciousness of it, which is true of every grace; and because of the extensiveness of it, reaching to head and members, to Christ and all his saints, the meanest and lowest of them; and because of its fragrancy and sweet odour to all that are sensible of it; and because of its delightful, cheering, and refreshing nature; like ointment and perfume it rejoices the heart; yea, the worst things said, or reproofs given, in brotherly love, are like oil, pleasant and useful, ( Proverbs 27:9 ) ( Psalms 141:5) ; and is as necessary for the saints, who are all priests unto God, to offer up their spiritual sacrifices; particularly that of prayer, which should be “without wrath”, as well as without doubting; and to do all other duties of religion, which should spring from charity or love; as the anointing oil was to Aaron and his sons, in order to their officiating in the priest’s office.” John Gill
