Psalmorum 133

1 canticum graduum David ecce quam bonum et quam iucundum habitare fratres in unum

[A Song of Ascents. By David.] See how good and how pleasant it is for brothers to live together in unity.

2 sicut unguentum in capite quod descendit in barbam barbam Aaron quod descendit in ora vestimenti eius

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 sicut ros Hermon qui descendit in montes Sion quoniam illic mandavit Dominus benedictionem et vitam usque in saeculum

like the dew of Hermon, that comes down on the hills of Zion: for there the LORD gives the blessing, even life forevermore.
