Song of Ascents.
Of David. Psalm 133
1 Behold, how good and pleasant it is when brethern dwell in unity!
2 It is like the precious oil on the head, running down on the beard, on the beard of Aaron, running down on the collar of his robes!
3 It is like the dew of Hermon, which falls on the mountains of Zion! For there the LORD has commanded the blessing, life forevermore.
The first verse is beloved by many, and contained in favorite praise songs.
How lovely if we could hear the joyous voices of Levites on this fourteenth step of their ascent.
“. . .unity among brethren, whether civil or religious, is productive both of profit and pleasure. Of profit, because therein consists the welfare and security of every society; of pleasure, because mutual love is the source of delight, and the happiness of one becomes, in that case, the happiness of all. It is unity alone which gives beauty, as well as strength, to the state; which renders the church, at the same time, fair as the moon, and terrible as an army with banners, Song of Solomon 6:10.” — Horne, as quoted in Benson Commentary.
