Psalm 133 Revised Standard Version Catholic Edition (RSVCE)
The Blessedness of Unity
A Song of Ascents.
133 Behold, how good and pleasant it is
when brothers dwell in unity!
2 It is like the precious oil upon the head,
running down upon the beard,
upon 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 for evermore.
