Psalm 133

133 See how good and how pleasant it is
for brothers to live together in unity!
2 It is like the precious oil on the head,
that ran down on the beard,
even Aaron’s beard,
that came down on the edge of his robes,
3 like the dew of Hermon,
that comes down on the hills of Zion;
for there Yahweh gives the blessing,
even life forever more.
