If you’ve ever looked through the table of contents in your Bible, you may have wondered, “What is the longest book in the Bible by chapters?” It’s a common question for Bible readers, students, and anyone beginning to explore Scripture. Knowing the structure of the Bible can deepen your appreciation for how God’s Word is organized and encourage you to study it more confidently.
The answer is the Book of Psalms. With 150 chapters, Psalms is the longest book in the Protestant Bible by chapter count. It is also the Bible’s longest collection of prayers, songs, and poems, expressing a wide range of human emotions—from joy and thanksgiving to sorrow, repentance, and unwavering trust in God.
Biblical Background:What Is the Longest Book in the Bible by Chapters
The Book of Psalms contains 150 chapters and is found in the Old Testament. It is a collection of sacred songs and prayers written over several centuries by various authors, including David, Asaph, the Sons of Korah, Solomon, Moses, and others.
Many of the psalms were originally written for worship in Israel and continue to inspire Christians today. They cover themes such as praise, repentance, thanksgiving, wisdom, God’s kingship, and hope in times of suffering.
One of the most beloved passages is Psalm 23:1 (NIV):
“The LORD is my shepherd, I lack nothing.”
Another well-known verse is Psalm 119:105 (NIV):
“Your word is a lamp for my feet, a light on my path.”
Psalm 119 is itself the longest chapter in the Bible, containing 176 verses, and beautifully celebrates the value of God’s Word.
