Here see, I. What it is that is commended - brethren's dwelling together in unity, not only not quarrelling, and devouring one another, but delighting in each other with mutual endearments, and promoting each other's welfare with mutual services. Sometimes it is chosen, as the best expedient for preserving peace, that brethren should live asunder and at a distance from each other; that indeed may prevent enmity and strife (Gen 13:9), but the goodness and pleasantness are for brethren to dwell together and so to dwell in unity, to dwell even as one (so some read it), as having one heart, one soul, one interest. David had many sons by many wives; probably he penned this psalm for their instruction, to engage them to love another, and, if they had done this, much of the mischief that arose in his family would have been happily prevented. The tribes of Israel had long had separate interests during the government of the Judges, and it was often of bad consequence; but now that they were united under one common head he would have them sensible how much it was likely to be for their advantage, especially since now the ark was fixed, and with it the place of their rendezvous for public worship and the centre of their unity. Now let them live in love.

II.How commendable it is: Behold, how good and how pleasant it is! It is good in itself, agreeable to the will of God, the conformity of earth to heaven. It is good for us, for our honour and comfort. It is pleasant and pleasing to God and all good men; it brings constant delight to those who do thus live in unity. Behold, how good! We cannot conceive or express the goodness and pleasantness of it. Behold it is a rare thing, and therefore admirable. Behold and wonder that there should be so much goodness and pleasantness among men, so much of heaven on this earth! Behold it is an amiable thing, which will attract our hearts. Behold it is an exemplary thing, which, where it is, is to be imitated by us with a holy emulation.

III.How the pleasantness of it is illustrated.

1.It is fragrant as the holy anointing oil, which was strongly perfumed, and diffused its odours, to the great delight of all the bystanders, when it was poured upon the head of Aaron, or his successor the high priest, so plentifully that it ran down the face, even to the collar or binding of the garment, Psa 133:2. (1.) This ointment was holy. So must our brotherly love be, with a pure heart, devoted to God. We must love those that are begotten for his sake that begat, Jo1 5:1. (2.) This ointment was a composition made up by a divine dispensatory; God appointed the ingredients and the quantities. Thus believers are taught of God to love one another; it is a grace of his working in us. (3.) It was very precious, and the like to it was not to be made for any common use. Thus holy love is, in the sight of God, of great price; and that is precious indeed which is so in God's sight. (4.) It was grateful both to Aaron himself and to all about him. So is holy love; it is like ointment and perfume which rejoice the heart. Christ's love to mankind was part of that oil of gladness with which he was anointed above his fellows. (5.) Aaron and his sons were not admitted to minister unto the Lord till they were anointed with this ointment, nor are our services acceptable to God without this holy love; if we have it not we are nothing, Co1 13:1, Co1 13:2.

2.It is fructifying. It is profitable as well as pleasing; it is as the dew; it brings abundance of blessings along with it, as numerous as the drops of dew. It cools the scorching heat of men's passions, as the evening dews cool the air and refresh the earth. It contributes very much to our fruitfulness in every thing that is good; it moistens the heart, and makes it tender and fit to receive the good seed of the word; as, on the contrary, malice and bitterness unfit us to receive it, Pe1 2:1. It is as the dew of Hermon, a common hill (for brotherly love is the beauty and benefit of civil societies), and as the dew that descended upon the mountains of Zion, a holy hill, for it contributes greatly to the fruitfulness of sacred societies. Both Hermon and Zion will wither without this dew. It is said of the dew that it tarrieth not for man, nor waiteth for the sons of men, Mic 5:7. Nor should our love to our brethren stay for theirs to us (that is publican's love), but should go before it - that is divine love.

IV.The proof of the excellency of brotherly love. Loving people are blessed people. For, 1. They are blessed of God, and therefore blessed indeed: There, where brethren dwell together in unity, the Lord commands the blessing, a complicated blessing, including all blessings. It is God's prerogative to command the blessing, man can but beg a blessing. Blessings according to the promise are commanded blessings, for he has commanded his covenant for ever. Blessings that take effect are commanded blessings, for he speaks and it is done. 2. They are everlastingly blessed. The blessing which God commands on those that dwell in love is life for evermore; that is the blessing of blessings. Those that dwell in love not only dwell in God, but do already dwell in heaven. As the perfection of love is the blessedness of heaven, so the sincerity of love is the earnest of that blessedness. Those that live in love and peace shall have the God of love and peace with them now, and they shall be with him shortly, with him for ever, in the world of endless love and peace. How good then is it, and how pleasant!

As the dew of Hermon, and as the dew that descended upon the mountains of Zion,.... Hermon was a very high hill beyond Jordan; the Sidonians called it Sirion, and the Amorites Shenir, Deu 3:8; hence Shenir and Hermon are mentioned together, Sol 4:8; and sometimes Sion or Seon, Deu 4:48; and is the Zion here intended; for the dew of Hermon could never descend on the mountain of Zion near Jerusalem, which was a hundred miles distant; besides Zion was but one mountain, these many. Hermon was remarkable for its dew, which still continues: a traveller (c), one of our own country, and whose fidelity is to be depended on, lying in tents near this hill one night, says,

"we were sufficiently instructed by experience what the holy psalmist means by the dew of Hermon; our tents being as wet with it as if it had rained all night.''

The mountains of Zion were those that were near to Zion, and not the mountain itself, those that were round about Jerusalem, on which the dew also fell in great plenty; and to which unity among brethren is here compared, because it comes from God in heaven, as the dew does. Saints are taught of God to love one another; contentions and quarrels come from lusts within, but this comes from above, from the Father of lights; and, because of its gentle nature, this makes men pure, and peaceable, and gentle, and easy to be entreated; as the dew falls gently in a temperate and moderate air, not in stormy and blustering weather: and because of its cooling nature; it allays the heats and animosities in the minds of men; and because it makes the saints fruitful, and to grow and increase in good works;

for there the Lord commanded the blessing; either in the mountains of Zion; so Kimchi: and if Mount Zion is meant by it, the church, often signified thereby, is the dwelling place of the Lord; here he records his name and blesses; here his word is preached, which is full of blessings; and here ordinances are administered, which are blessed of God to his people. Theodoret thinks some respect is had to the pouring down of the Spirit on the apostles in Jerusalem, on the day of Pentecost: but rather the sense is, where brethren dwell together in unity, there the God of love and peace is; the Gospel of the grace of God is continued; and the ordinances of it made beneficial to the souls of men, they meeting together in peace and concord; see Co2 13:11. God is said to "command the blessing" when he promises it, and makes it known to his people, or bestows it on them, Psa 105:8;

even life for evermore: the great blessing of all, which includes all others, and in which they issue, the promise of the covenant, the blessing of the Gospel; which is in the hands of Christ, and comes through him to all his people; to the peacemakers particularly, that live in love and peace; these shall live for ever in a happy eternity, and never die, or be hurt of the second death.
