Psalms 133

1 A Song of the Ascents, by David. Lo, how good and how pleasant The dwelling of brethren — even together!

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

2 As the good oil on the head, Coming down on the beard, the beard of Aaron, That cometh down on the skirt of his robes,

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 As dew of Hermon — That cometh down on hills of Zion, For there Jehovah commanded the blessing — Life unto the age!

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.
