Septuagint Isaiah
LXX / Hēsaias — The Bible of the early church
About This Tradition
The Septuagint Isaiah was the form of Isaiah read by the early church. The New Testament cites Isaiah more than any other prophet, and the great majority of those citations follow the LXX rather than the Hebrew — including almah rendered parthenos (“virgin”) at Isaiah 7:14, the Suffering Servant of chapter 53 cited at Acts 8, Romans 10, and 1 Peter 2, and the cornerstone of 28:16 cited at Romans 9 and 1 Peter 2.
What you see below is a verse-by-verse comparison: where does the Septuagint agree with the Masoretic tradition, and where does it differ? Christological readings, Servant Songs, and the eschatological vocabulary that became standard in apostolic preaching all begin here. Every variant is documented. Nothing is hidden.
