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

2 like/as oil [the] pleasant upon [the] head to go down upon [the] beard beard Aaron which/that to go down upon lip: edge measure his

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 like/as dew (Mount) Hermon which/that to go down upon mountain Zion for there to command LORD [obj] [the] blessing life till [the] forever: enduring

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.
