"When Brothers Dwell in Unity
A Song of Ascents. Of David.
133 Behold, how good and pleasant it is
when brothers dwell in unity![a]
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."
