Executive Summary: Zechariah → Bengali Language Package

The bottom line: Zechariah can be translated into Bengali using the established Christian-register vocabulary already fixed by the Romans baseline, extended with 64 new terms this book requires — but 7 of those new terms are Critical-risk and 22 are High-risk, concentrated in exactly the material this curriculum is built around: the core passage (9:9-10), the pierced-one prophecy (12:10), and the divine-name/oneness material (14:9). Every one of those requires human theologian sign-off before Phase 2 ships.

Why it matters

Zechariah is the most NT-quoted minor prophet in this pipeline’s queue — four of its passages (9:9; 11:12-13; 12:10; 13:7) are directly quoted of Jesus in the Gospels. Every rendering decision made here will be reused verbatim when those Gospel passages are processed later. Get the Bengali wrong here, and the error propagates forward into the Gospels curriculum automatically. Zechariah also sits closer to the two dominant Bengali religious traditions than Romans did: it introduces the tetragrammaton (সদাপ্রভু), a literal Jerusalem temple (মন্দির), prophetic “vision” (দর্শন — a live Hindu devotional word), and an absolute divine-oneness affirmation (14:9) that reads almost verbatim as Islamic tawhid. None of these collision points existed in the Romans baseline.

Key findings

• 27 doctrines identified across all 14 chapters (full-book coverage confirmed, no chapter silently omitted): 5 Critical, 15 High, 5 Medium, 2 Low.
• 20 of 27 doctrines (74%) require mandatory human theologian review; only 2 are automated-review-only.
• 92 total terms now in the Bengali translation memory for this curriculum: 28 inherited exactly from the Romans baseline (ঈশ্বর, প্রভু, ধার্মিকতা, পরিত্রাণ, পবিত্র, নিয়ম, etc.) plus 64 new Zechariah-specific terms.
• Of the 64 new terms: 7 are Critical risk, 22 are High risk, 25 are Medium, 10 are Low.
• Combined with inherited baseline Criticals/Highs, the curriculum carries 18 Critical-risk terms and 32 High-risk terms requiring absolute glossary enforcement with zero tolerated substitution.
• Two genuine terminology gaps were caught only during the linguistic gap analysis and had to be added late: মন্দির (temple), previously absent from the core glossary despite being the most Hindu-coded common noun in the book, and Zechariah 14:5’s “holy ones,” which must reuse the baseline’s পবিত্র লোক and never সাধুগণ.

Risks

• The core passage itself is double-jeopardy. Zechariah 9:9’s “having salvation” (নোֹשָׁע) is grammatically passive in Hebrew — the king is himself vindicated by God, not merely a victor by his own strength — and a naive active-voice Bengali rendering silently erases this. The same verse’s “donkey” must avoid গাধা, live Bengali insult slang, or the peace-symbolism central to the whole doctrine collapses into an unintended joke.
• 12:10’s pierced-one prophecy is the single highest-risk verse in the book. Its Hebrew grammar shifts abruptly from “they look on ME” to “whom they have pierced HIM” — the verse’s entire Trinitarian and atonement force depends on preserving that shift, which has no natural Bengali syntactic equivalent and will be tempting to “fix.”
• 14:9’s oneness affirmation is a live apologetic fault line, not a dormant one. It reads as near-verbatim common ground with Islamic tawhid and can be, and has been, used by Muslim-background readers to argue against the Trinity if the mandatory compatibility note is dropped.
• 13:1 deliberately violates the baseline’s own safety rule. The baseline separates পাপ (moral sin) from অশুচিতা (ritual impurity) specifically to avoid Hindu shuddhi collision — but Zechariah’s Hebrew text pairs them in one verse on purpose, requiring a note that overrides, without contradicting, the baseline’s general caution.
• New coined vocabulary (অন্তর্জ্বালা for “zeal”) has zero prior reader familiarity and risks silent reversion to the wrong, doctrinally damaging ঈর্ষা (petty envy) if not reinforced at every occurrence, not just the first.

Opportunities

• Zechariah’s Day-of-the-LORD eschatology (ch. 14) and its “testing/refining by fire” theme (13:8-9) both land on genuinely strong common ground with Islamic Yawm al-Qiyamah expectation and tawakkul (reliance on God over human strength) — real bridge-building material if handled with the required framing notes rather than avoided.
• The book’s shared vocabulary for fasting (উপবাস) across Hindu, Muslim, and Christian practice offers an accessible entry point for teaching Zechariah 7’s ethics-over-ritual message to a mixed audience.
• Because four Zechariah passages are pre-identified NT quotation sources, this Language Package gives the Gospels curriculum a running head start: the harmonization table in 12_ai_translation_requirements.md locks in consistent Bengali renderings now, before Matthew/John translation work even begins.

Recommended actions

1. Route all 7 Critical-risk and 22 High-risk new terms, plus the corresponding 20 Critical/High doctrines, through mandatory human theologian review before any Phase 2 batch ships — no exceptions, per the escalation rules in 12_ai_translation_requirements.md.
2. Lock the core-passage rendering of Zechariah 9:9-10 and the pierced-one rendering of 12:10 as fixed, curriculum-wide, non-negotiable strings before any other segment is processed, given their downstream reuse in a future Gospels curriculum.
3. Require the standing (not one-time) translator notes for অন্তর্জ্বালা (zeal), সদাপ্রভুর মন্দির (temple), দর্শন (vision), and the 14:9 Trinitarian-compatibility note at every occurrence, not merely the first — these are the terms most likely to silently drift back toward a doctrinally wrong default if reinforcement lapses.
4. Carry the six-row Zechariah-to-NT harmonization table forward into the intake package for whichever Gospel or Gospels-curriculum project is scheduled next.
