History note — why this app is Septuagint-first

Why LXX + GNT are the roots

Not a preference — a timeline. Logos buries LXX because modern English Bibles are licensed off MT-based translations. Metanoia buries MT because the church studied in Greek before Hebrew had vowels.

3rd–1st c. BCE — LXX

Torah in Alexandria (~280 BCE, Letter of Aristeas), rest by 1st c. BCE for Greek-speaking synagogues (Philo, Josephus). The diaspora's Bible.

Source you share with septcheck & Fedora LXXG: `nathans/lxx-swete` (Swete 1887–1930 word-per-line).

1st c. CE — NT quotes LXX

~70–80% of ~300 OT citations follow LXX wording verbatim. Isa 7:14 עַלְמָה → παρθένος → Matt 1:23; Amos 9:11-12/Acts 15:16-17; Ps 40:6/Heb 10:5.

The disciples heard Greek LXX in synagogues; consonantal Hebrew had no niqqud yet.

7th–10th c. CE — MT pointed

Consonantal text stabilized 1st–2nd c. CE; Tiberian vocalization (Ben Asher/Ben Naphtali) adds niqqud + cantillation 7th–10th c. Leningrad/WLC = 1008 CE.

DSS (1947) often side with LXX Vorlage over MT: Deut 32:8 בני אלהים/υἱῶν θεοῦ vs בני ישראל, Jer length.

So Logos got it backwards for study

Tyndale→KJV cemented MT English; ESV/NASB/NKJV licensing keeps it default in premium tools. That's a publishing fact, not a textual argument. Metanoia keeps MT as a comparison pane (src/models/config.zig:142 defaults ot_source="lxx", checkbox at src/main.zig:1191 Advanced) — buried Logos-style, but in the other direction.

Both matter — ordered correctly.

Greek for NT background and early-church reading; Hebrew for later Masoretic precision and consonantal variants (see DSS). The app pairs LXXE English + LXX interlinear so load_chapter_into_study (src/main.zig:403-417) and lexicon (src/bible_db.zig:584-598 ORDER BY source → GNT<LXX<MT) stay in one language for ordered study. Lexicon transliteration fix (lxx_translit.py:72) closes the art⊂amart- collision.
