Septuagint Psalms
LXX / Psalmoi — The Greek Psalter of the early church
About This Tradition
The Septuagint Psalter was the prayer book of the early church. Its numbering system diverges from the Hebrew (LXX Psalm 9 = MT Psalms 9-10; LXX Psalms 10-112 are one number lower than MT; LXX Psalm 147 = MT Psalms 146-147). It includes Psalm 151, absent from the Masoretic tradition. The New Testament cites the Psalms more than any other book; Hebrews 1, Acts 2, and Romans 3 all draw their Christological argument from LXX phrasing.
What you see below is a chapter-by-chapter comparison: where does the Septuagint agree with the Masoretic tradition, and where does it differ? Numbering offsets, additional superscriptions, and the Christologically-loaded vocabulary that shaped apostolic preaching are all surfaced. Every variant is documented. Nothing is hidden.
