Outline

  1. The gateway: Torah and the king Chapters 1–2

    Psalm 1 blesses the one who delights in God's instruction, and Psalm 2 celebrates God's anointed king, introducing two threads that run through the whole book.

  2. Book I: David's prayers in trouble Chapters 3–41

    Mostly psalms of David, many of them laments and cries for rescue, alongside creation hymns like Psalms 8 and 19 and the trusting Psalm 23. It ends with a doxology in 41:13.

  3. Book II: Longing, repentance and the ideal king Chapters 42–72

    Opens with psalms of the sons of Korah, includes David's prayer of repentance in Psalm 51, and closes with Psalm 72, a prayer for the king.

  4. Book III: Crisis and the temple's ruin Chapters 73–89

    Psalms of Asaph and Korah wrestle with the prosperity of the wicked and national disaster. Psalm 89 ends asking why God's covenant with David seems broken.

  5. Book IV: The Lord reigns Chapters 90–106

    Beginning with a prayer of Moses, these psalms answer the crisis by proclaiming God as king and recalling his faithfulness through Israel's history.

  6. Book V: Thanksgiving, Torah and pilgrimage Chapters 107–145

    Includes the Hallel (113–118), the great Torah psalm 119, the Songs of Ascents (120–134), the exile lament 137 and a final collection of David's psalms.

  7. The closing Hallelujahs Chapters 146–150

    Five psalms that begin and end with “Praise the Lord” bring the book to a crescendo, calling on every living creature to join in.

What is the Book of Psalms about?

The Psalms are prayers and songs addressed to God or about God. Unlike most books of the Bible, they do not tell one story or build one argument. Instead they give words to people speaking to God in every circumstance: in danger and illness, after sin, in exile, at festivals, at a king's coronation, and in quiet trust.

Blessed is the man who does not walk in the counsel of the wicked, or set foot on the path of sinners, or sit in the seat of mockers. But his delight is in the Law of the LORD, and on His law he meditates day and night. He is like a tree planted by streams of water, yielding its fruit in season, whose leaf does not wither, and who prospers in all he does.

Psalm 1:1–3 · BSB

The Hebrew title of the book is Tehillim, meaning “praises,” while the English name comes from the Greek word for songs sung to stringed instruments. That fits the book's movement. Many psalms begin in distress, but the collection as a whole travels from lament toward praise, ending in a chorus of Hallelujahs.

Psalm 1 sets the tone by describing two ways of life: the person rooted in God's instruction, compared to a fruitful tree, and the wicked, who are as rootless as husks in the wind. Psalm 2 then presents God's anointed king. Together they prepare the reader for a book about living faithfully under God's rule.

How is the Book of Psalms organized?

The Psalter is divided into five books: Psalms 1–41, 42–72, 73–89, 90–106 and 107–150. Each of the first four ends with a short blessing of God (41:13, 72:18–19, 89:52 and 106:48), and Psalms 146–150 serve as the closing praise for the whole collection. Ancient Jewish readers saw a parallel with the five books of Moses.

Let everything that has breath praise the LORD! Hallelujah!

Psalm 150:6 · BSB

The books also show a rough storyline. Books I and II center on David, and a closing note at 72:20 marks the end of his collection. Book III reflects national catastrophe, and Psalm 89 laments that the promises to David seem to have failed. Books IV and V respond by proclaiming that the Lord himself reigns and by leading the people back to thanksgiving, pilgrimage and praise.

Within this frame you meet several kinds of psalms. Hymns praise God for who he is and what he has made; laments, the most common type, cry out for help; thanksgiving psalms celebrate rescue; royal psalms such as 2, 45, 72 and 110 concern the king; and wisdom psalms such as 1, 37 and 119 reflect on how to live. Some are acrostics, with lines beginning with successive letters of the Hebrew alphabet, and smaller groups include the Hallel (113–118) and the Songs of Ascents (120–134), sung by pilgrims going up to Jerusalem.

What are the main themes of the Psalms?

God as king and creator stands at the center. The Psalms praise the Lord who made the heavens and the earth, rules the nations and cares for the poor, the widow and the stranger. Psalms 93 and 95–99 repeat that the Lord reigns, even when earthly kings fail.

God is our refuge and strength, an ever-present help in times of trouble. Therefore we will not fear, though the earth is transformed and the mountains are toppled into the depths of the seas, though their waters roar and foam and the mountains quake in the surge. Selah

Psalm 46:1–3 · BSB

Trust in God's steadfast love runs through nearly every psalm. It is his loyal love for the people bound to him by covenant, and psalmists appeal to it when they have nothing else to stand on. Psalm 46 trusts God to be a safe place even when the world seems to fall apart.

Other threads include delight in God's instruction (Psalms 1, 19 and 119), honest confession of sin (Psalms 32 and 51), the hope placed in David's line, Zion and the temple as the place of God's presence, and the remembrance of God's deeds in Israel's history (Psalms 78, 105 and 106). The book also cares deeply about justice, asking God again and again to defend the oppressed.

Why are there so many sad psalms?

If you are hurting, the Psalms make room for you. About a third of the book is lament: prayers from people who feel abandoned, sick, betrayed, guilty or afraid. They show that it is not a lack of faith to tell God exactly how bad things are.

My God, my God, why have You forsaken me? Why are You so far from saving me, so far from my words of groaning? I cry out by day, O my God, but You do not answer, and by night, but I have no rest.

Psalm 22:1–2 · BSB

Laments usually follow a pattern: a cry to God, a description of the trouble, a plea for help, and often a turn toward trust or a promise to praise. Psalm 13 moves in just six verses from feeling forgotten by God to joyful trust. Psalm 22 begins with a cry of abandonment and ends with praise spreading to the nations.

Not every lament resolves. Psalm 88 ends in darkness, with no turn to praise at all. Its place in Scripture tells sufferers that even prayers without answers are still prayers, spoken to the God who listens.

What are the most famous psalms?

Psalm 23, the Shepherd Psalm, is probably the best loved, picturing God as a shepherd who provides for his people and stays with them through danger. Psalm 51, traditionally linked with David's repentance after his sin with Bathsheba, is the classic prayer of confession and renewal.

The LORD is my shepherd; I shall not want. He makes me lie down in green pastures; He leads me beside quiet waters. He restores my soul; He guides me in the paths of righteousness for the sake of His name. Even though I walk through the valley of the shadow of death, I will fear no evil, for You are with me; Your rod and Your staff, they comfort me.

Psalm 23:1–4 · BSB

Create in me a clean heart, O God, and renew a right spirit within me. Cast me not away from Your presence; take not Your Holy Spirit from me. Restore to me the joy of Your salvation, and sustain me with a willing spirit.

Psalm 51:10–12 · BSB

Other well-known psalms include Psalm 8 on human dignity in creation, Psalm 19 on the heavens and the law, Psalm 90 on human frailty, Psalm 91 on God's protection, Psalm 103 on God's forgiving love, Psalm 121 on help from the Lord, Psalm 137 on grief in exile, and Psalm 139 on being fully known by God. Psalm 119, with 176 verses, is the longest chapter in the Bible.

How do the Psalms fit in the whole Bible?

The Psalms belong to the Writings in the Hebrew Bible and to the poetic or wisdom books in Christian Bibles, alongside Job, Proverbs, Ecclesiastes and the Song of Songs. They echo the rest of the Old Testament, retelling creation, the exodus, the covenant with David, the temple and the exile in the language of prayer.

The stone the builders rejected has become the cornerstone. This is from the LORD, and it is marvelous in our eyes.

Psalm 118:22–23 · BSB

The New Testament quotes the Psalms more than almost any other Old Testament book. Jesus prays Psalm 22 on the cross (Matthew 27:46), Psalm 110:1 is used repeatedly to speak of Christ's exaltation, Psalm 2:7 appears in Acts 13 and Hebrews 1, and Psalm 118:22 is applied to Jesus as the rejected stone. Christians have read many psalms, especially the royal ones, as pointing to the Messiah, while Jewish tradition reads them in light of David's line and the hope of a future anointed king.

The Psalms have also shaped worship for well over two thousand years. They are sung in synagogues, prayed daily in the Catholic Liturgy of the Hours, read through each week in Orthodox services, and set to music in Protestant hymnals and metrical psalters. For many believers, the Psalms are where they first learn how to pray.

Questions people ask

Why do some Bibles number the Psalms differently?

The Hebrew text and the ancient Greek translation (the Septuagint) divide a few psalms differently, so from Psalm 10 to Psalm 147 the Greek numbering is usually one lower. Many older Catholic and Orthodox Bibles follow the Greek numbering, while most Protestant and modern Catholic Bibles follow the Hebrew. So the psalm many know as Psalm 23 appears as Psalm 22 in some editions.

Is there a Psalm 151?

Yes, in some traditions. The Septuagint includes a short Psalm 151 about David's anointing and his victory over Goliath, and Orthodox Bibles include it. Catholic and Protestant Bibles follow the 150-psalm Hebrew collection, though a Hebrew form of Psalm 151 was found among the Dead Sea Scrolls.

What are the psalms that curse enemies?

Some psalms, such as Psalm 109 and the end of Psalm 137, ask God to punish enemies in harsh terms; they are often called imprecatory psalms. Many readers see them as honest cries of people who have suffered real violence, handing their rage and their demand for justice to God rather than taking revenge themselves. Christian traditions differ on how to pray them, but they remain part of the Psalter's witness to the full range of human prayer.

How should I start reading the Psalms?

Many people read one psalm a day, or five a day to finish the book in a month. It can help to notice what kind of psalm you are reading, whether praise, lament or thanksgiving, and to pray it in your own words afterward. Psalms 1, 23, 46, 51, 103 and 139 are common starting points.
