I don’t know where it originated, but a friend recently gave me a very helpful handout on the Psalms. It lists every Psalm with a few words summarising what it’s about, and some general overviews. I want to share one of them today.
It is helpful to see a broad brush topical similarity in how the Psalms have been collated with the Pentateuch, the first five books of the Bible:
Book 1 – Psalms 1-41 – Songs of worship: cf. Genesis – the story of humanity and creation.
Closing doxology is Ps.41:13
Book 2 – Psalms 42-72 – Hymns of national interest (1): cf. Exodus – the story of deliverance and redemption.
Closing doxology is Ps.72:18-19
Book 3 – Psalms 73-89 – Hymns of national interest (2): cf. Leviticus – The story of worship and sanctuary.
Closing doxology is Ps.89:52
Book 4 – Psalms 90-106 – Anthems of praise (1): cf. Numbers – The story of the wilderness wanderings.
Closing doxology is Ps.106:48
Book 5 – Psalms 107-150 – Anthems of praise (2) (2): cf. Deuteronomy – The story of Scripture and praise.
Closing doxology is the whole of Ps.150
