Psaumes 133

1 Cantique graduel. De David. Voyez! qu'il est beau, qu'il est doux que des frères vivent ainsi dans l'union!

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

2 Telle l'huile exquise, qui de la tête descend sur la barbe, sur la barbe d'Aaron, qui descend jusqu'au bord de son vêtement;

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 telle la rosée de l'Hermon, et celle qui descend sur les montagnes de Sion! Car c'est là que l'Éternel envoie bénédiction et vie pour l'éternité.

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.
