Why it matters

Joel is this project’s first Old Testament, Hebrew-original curriculum, and its core passage (2:28–32) is quoted verbatim twice in the New Testament (Acts 2:17–21; Romans 10:13) — meaning Bengali readers will encounter this exact language again from two directions. Get সদাপ্রভু (YHWH), ঢেলে দেব (pour out the Spirit), and the Joel 2:32/Romans 10:13 salvation clause wrong here, and the error propagates into every future Acts and Romans-adjacent curriculum this pipeline touches. Joel also sits at an unusually high collision point with both dominant Bengali religious traditions: its central doctrine (the Day of the Lord) has a structural rival in both Hindu cyclical-cosmology and Islamic qiyamat frameworks, and its central image (the Spirit poured out) has a structural rival in Hindu puja libation and darshan vocabulary.

Key findings

• 18 distinct doctrines identified across the full book (chapters 1–3, no chapter silently skipped); 3 Critical + 10 High = 13 require mandatory human theologian review, 4 require native speaker review, 1 is automated-only.
• 42 new Joel-specific terms added to translation memory beyond the baseline Romans package; 6 rated Critical, 10 rated High — bringing the combined Critical-term count (Joel-new + inherited baseline Critical terms: ঈশ্বর, পবিত্র আত্মা, পরিত্রাণ, প্রভু) to 10 Critical-risk terms, and the combined High-term count (Joel-new + inherited: পবিত্র, আহুত, আহ্বান, পাপ, নিয়ম) to 15 High-risk terms requiring theologian sign-off before Phase 2 release.
• The single highest-stakes translation decision in the whole book is the two-directional “calling” fence in Joel 2:32 — human-to-God (ডাকা) and God-to-human (আহ্বান করা) occur back-to-back in one verse, and this verse is also the exact text Romans 10:13 quotes, making it the load-bearing junction between this curriculum and the existing baseline.
• সদাপ্রভু (the covenant name) must never collapse into the baseline’s প্রভু — a live risk precisely because translators trained on the Romans package will have প্রভু as a reflex.

Risks

• Syncretism risk (Critical): ঢেলে দেব (pour out the Spirit) reads through Hindu puja-libation imagery unless direction-of-action is fenced; দর্শন (vision) reads through Hindu bhakti darshan unless fenced; সদাপ্রভুর দিন reads through Hindu cyclical yuga cosmology or Islamic কিয়ামত unless the covenant-name anchor is preserved every time.
• Doctrinal flattening risk (High): চেসেদ (covenant-loyalty love, 2:13) and קַנָּא (divine jealousy, 2:18) both have only compromised or absent single-word Bengali equivalents (দয়া alone flattens to generic pity; ঈর্ষা is outright sinful envy) — both require mandatory paraphrase and translator notes, not silent single-word substitution.
• Lexical gap risk (High): Bengali has one word (পঙ্গপাল) for Hebrew’s four distinct locust terms, risking loss of both the escalating four-wave devastation image and the explicit “his army” (divine-agency) framing of the plague, which could otherwise read as ordinary natural disaster.
• Cross-curriculum consistency risk (Critical): if Joel 2:32 and Romans 10:13 are ever translated by different workers without cross-checking, the pipeline could produce two non-identical Bengali renderings of the same quoted verse.

Opportunities

• Joel’s brevity (73 verses) makes it a tractable proving ground for this pipeline’s first OT/Hebrew-source curriculum before scaling to longer OT books.
• The চেসেদ compound gloss (দয়া / নিয়মের বিশ্বস্ত প্রেম) is explicitly recommended for promotion into a shared cross-curriculum translation memory, since it will recur across Ruth, Hosea, and Psalms.
• The সদাপ্রভু vs. প্রভু fence, once firmly established here, becomes a reusable template for every future OT curriculum in this pipeline.

Recommended actions

1. Route all 13 Critical/High doctrines and all 16 Critical/High terms through human theologian review before Phase 2 segment translation begins, per assets/doctrine_risk_registry.json and assets/translation_memory.json.
2. Hold Joel 2:28–32 segments for joint review against the Romans Language Package’s Romans 10:13 rendering before finalizing either — do not release one without confirming the other.
3. Enforce mandatory [TRANSLATOR NOTE] flags at first occurrence for ঢেলে দেব, দর্শন, সদাপ্রভুর দিন, গভীর অনুরাগ, চেসেদ/দয়া, পঙ্গপাল, and যিহোশাফটের উপত্যকা, per 12_ai_translation_requirements.md.
4. Carry the সদাপ্রভু/প্রভু directional discipline and the ডাকা/আহ্বান করা two-directional fence into Phase 2 validation as automated pre-release checks, not just reviewer guidance.
5. Promote চেসেদ (দয়া / নিয়মের বিশ্বস্ত প্রেম) to the shared cross-curriculum glossary ahead of any future Ruth, Hosea, or Psalms curriculum.
