Psalms 133

1 A song of ascents, of David. Behold, how good and how pleasant it is for brothers to live together!

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

2 It is like fine oil on the head pouring down on the beard— Aaron's beard, and then it pours down on the collar 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 It is like the dew of Hermon which falls on the mountains of Zion. For there Yahweh commanded the blessing— life forevermore.

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.
