Codex — Scholarly Bible Study Across Time, Language, and Tradition
Codex is a free, scholarly environment for reading Scripture across translations, languages, and more than two thousand years of textual history. See how a single passage travelled from its ancient Hebrew and Greek source texts into the translations read today.
Read and compare passages side by side in the Reading view, explore the geographic spread of Bible translations on an interactive timeline in the Translation Atlas, and trace the genealogy of versions from their source manuscripts in the Lineage Tree.
Study the textual traditions and ancient manuscripts behind every rendering in Scholarly Sources, then build a vocabulary list from biblical Hebrew and Greek, run spaced-repetition drills, and dig into the morphology and grammar of the original languages in the Learn section.
