TEV:

1. How wonderful it is, how pleasant, for God’s people to live together in harmony!
2. It is like the precious anointing oil running down Aaron’s head and beard, down to the collar of his robes.
3. It is like the dew on Mount Hermon, falling on the hills of Zion. That is where the Lord has promised his blessing – life that never ends.

NIV:

1. How good and pleasant it is when brothers live together in unity!
2. It is like precious oil poured on the head, running down on the beard, running down on Aaron's beard, down upon the collar of his robes.
3. It is as if the dew of Hermon were falling on Mount Zion. For there the LORD bestows his blessing, even life forevermore.

KJV:

1. Behold, how good and how pleasant [it is] for brethren to dwell together in unity!
2. [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;
3. 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.

Matthew Henry Commentary:

This psalm is a brief encomium on unity and brotherly love, which, if we did not see the

miseries of discord among men, we should think needless; but we cannot say too much, it were well if we could say enough, to persuade people to live together in peace. Some conjecture that David penned this psalm upon occasion of the union between the tribes when they all met unanimously to make him king. It is a psalm of general use to all societies, smaller and larger, civil and sacred. Here is,

I. The doctrine laid down of the happiness of brotherly love

# 1

II. The illustration of that doctrine, in two similitudes

# 2, 3

III. The proof of it, in a good reason given for it

# 3

and then we are left to make the application, which we ought to do in singing it, provoking ourselves and one another to holy love. The contents of this psalm in our Bibles, are short, but very proper; it is "the benefit of the communion of saints."
