Psalmorum 133

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

It is very good and very pleasant for God’s people to gather together harmoniously.

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

It is [as delightful as] the precious/expensive ([olive] oil/perfume) that runs down from [the Supreme Priest] Aaron’s head onto his beard [when he is anointed] and runs down onto the collar of his robes.

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

Gathering together harmoniously [is as delightful] as the dew [that falls] on Hermon [Mountain] and the dew that falls on the hills near Zion [Hill]. Yahweh has promised to bless [his people there in Jerusalem] [by giving them] everlasting (OR, a long-lasting) life.
