One hundred and fifty poems, gathered over several centuries into a single book. The Psalter is an anthology before it is anything else, and most of the questions worth asking about it follow from that one fact.
What the book is
Psalms is a collection of Hebrew religious poetry. There is no narrative running through it, no prophet with a biography, no sequence of events to check. Most of the poems are addressed to God rather than spoken by God to an audience, which makes the book unusual within the canon: it is largely the human side of the conversation. The pieces vary enormously in length and in temper, and reading them as one voice flattens that.
How it is put together
The Psalter is divided into five books: 1–41, 42–72, 73–89, 90–106 and 107–150. The division is not a printer’s convenience imposed later but is marked in the text, because the first four books each close with a short doxology — a formula of blessing with a concluding “amen” — that does not belong to the psalm it is attached to. The fifth has no such tag; Psalm 150 in its entirety serves as the closing doxology of the whole.
Underneath that frame sit older, smaller collections assembled before the whole was: groups attributed to Asaph and to the sons of Korah, the songs of ascents at 120 to 134, the festival Hallel at 113 to 118. The seams show. Psalm 72 ends “the prayers of David son of Jesse are ended”, yet psalms attributed to David appear repeatedly afterwards — what you would expect if a collection that once stopped there was later absorbed into a larger one. Across Psalms 42 to 83 the divine name YHWH is markedly less frequent and Elohim markedly more, a stretch usually called the Elohistic Psalter.
Form criticism sorts the poems by type rather than by author, and its categories organise the book better than its own arrangement does. The main ones:
- Lament — individual or communal complaint, the largest category.
- Thanksgiving — looking back on a rescue already accomplished.
- Hymn — praise without a specific occasion.
- Royal — poems about the reigning king.
- Enthronement — a group proclaiming that God reigns as king.
- Wisdom and torah — reflective poems on the two ways or on the law.
What “of David” does and does not assert
Most psalms carry a superscription naming a person, a musical direction or an occasion, and the commonest is the Hebrew phrase le-dawid, rendered “of David”. The difficulty is the prefixed letter lamed, which is doing the work of “of”. It can indicate authorship, but it can equally mean “belonging to”, “for”, “concerning”, or “in the collection associated with”. The same construction introduces Asaph and the sons of Korah, elsewhere described as guilds of temple singers rather than individual poets. The phrase is ambiguous in the language itself, before any question of history arises. The traditional position takes it as authorship; the mainstream critical position takes it as attribution to a Davidic collection. Both are readings of an ambiguous preposition.
A smaller group of headings supplies a setting from David’s life — fleeing from Absalom, the confrontation with Nathan after Bathsheba. These are the likeliest to be later additions, reading as a reader’s note connecting a poem to a story rather than as a poet’s own framing. Superscriptions also differ between textual traditions — the Greek attributes more psalms to David than the Hebrew does — which shows they were still being added while the book was being translated. Several of their technical terms, selah and maskil and miktam among them, have no agreed meaning.
Why a verse reference can differ between Bibles
Two readers looking up the same psalm number in different Bibles may find different poems, for mechanical rather than doctrinal reasons. The Greek tradition, followed by the Latin Vulgate, joins the Hebrew Psalms 9 and 10 into one and likewise joins 114 and 115, then splits the Hebrew 116 and the Hebrew 147 each into two. Through most of the Psalter the Greek and Latin number therefore runs one behind the Hebrew, the two realigning near the end; older Catholic Bibles and much liturgical writing follow the Greek. Verse numbers diverge for a second reason: where a psalm carries a superscription, printed Hebrew Bibles usually count it as verse 1, so an English verse number is often one lower than the Hebrew for the same line. The Greek tradition also carries an extra composition numbered 151 and marked as outside the count.
Where the external record touches it
Poetry does not leave the footprint a battle does. No inscription confirms a psalm; what the record supplies is genre context and manuscript evidence.
The Ugaritic tablets recovered at Ras Shamra on the Syrian coast preserve religious poetry in a Northwest Semitic language closely related to Hebrew, and they changed the study of the Psalter. They show that the parallelism the psalms are built on, along with a stock of fixed word pairs and several divine epithets, was standard Canaanite technique rather than an Israelite invention; Psalm 29 is the case usually discussed here. From Egypt, the Great Hymn to the Aten is routinely set beside Psalm 104, the two sharing a sequence of ideas about the sun and the ordering of creatures. Mesopotamian hymns and penitential prayers offer parallels for the lament form.
None of this establishes borrowing in a particular case; a shared regional idiom explains most of it. What it does establish is that the Psalter is a recognisable participant in an ancient Near Eastern literature of worship — context rather than corroboration, a distinction set out in what external attestation means.
The manuscript evidence is more direct. Psalms is among the best-represented books at Qumran, and the largest psalms scroll found there orders the later part of the book differently from the received text and includes compositions absent from the standard 150. Whether that is a variant edition or a liturgical selection is disputed; either way the shape of the book was not yet fixed everywhere when the copy was made.
The dating question
There is no single date for Psalms, and anyone offering one is answering a different question. Psalms are dated individually, on internal evidence, and the results spread widely: royal psalms are commonly argued to be court compositions from the monarchy, while Psalm 137 presupposes the exile. The collection reached its present form later, in the Second Temple period, on the mainstream reckoning. Dating a short poem is harder than dating a narrative, because poetry preserves archaic language deliberately and refers to events obliquely or not at all — see how we date a text.
Where to start
Read the closing verses of Psalms 41, 72, 89 and 106, one after another. The five-book structure becomes visible in about two minutes, and once it is the book stops looking like a heap and starts looking like an edited object. Then read Psalm 14 beside Psalm 53: two versions of one poem, both preserved, differing in a way that tells you something about the collections they came from. Corrections are logged at corrections.
