Read Psalms Chapter 133 from the World English Bible. Old Testament, 150 chapters total.
1 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.
