The importance of the Ndumu language
Having a Ndumu Bible translation is critically important for reaching the ~3,000–4,300 Bandumu people in Haut-Ogooué Province, eastern Gabon. The Bandumu live primarily around Franceville and along the Mpassa River. Ethnologue notes that while young people do use it as a first language, the language is not taught in schools. Urbanization around Franceville, where many traditional villages have been absorbed as city neighborhoods, accelerates the shift toward French.
For churches, missionary organizations, and faith communities throughout Haut-Ogooué Province, providing the Bible in Ndumu ensures that the Christian message reaches speakers in their heart language—the language in which they think, dream, and connect most deeply with spiritual truth. Though many Bandumu today speak French, the national language, reading or hearing Scripture in French creates a barrier for full comprehension and emotional engagement, especially for older speakers and those whose formal education was limited. Without a Ndumu translation, churches risk losing an entire generation of Bandumu believers who cannot access God's Word in the language of their identity and heritage.

This Ndumu translation in the wider community
Ndumu belongs to the Mbete language group within the broader Teke-Mbere Bantu cluster, with close relatives including Mbere (Mbede), Lembaama, and Kaning'i. Historical sources record several Ndumu dialects—Epigi, Kanandjoho, Kuya, and Nyani—and note that French colonizers adopted the Kuya dialect as a lingua franca among Ndumu speakers. Alexandre Biton's 1969 grammar and bilingual dictionary attest to historical mutual intelligibility with Mbede, and written materials were sometimes produced for both languages together. Ndumu uses Latin script. During the French colonial period, Ndumu held regional prestige: French administrators found it easier and more harmonious than neighboring languages, and it served as the official language of the Haut-Ogooué, used in missions, trade, and intertribal communication. Many Ndumu speakers worked as clerks and interpreters. Despite this former prominence, urbanization and French-language policy have driven sharp language decline, with the Bandumu now described as a nearly urbanized population and Ndumu having fewer and fewer native speakers.
This Ndumu translation in local churches
Missionary work among the Bandumu dates back at least to the mid-20th century, as evidenced by Alexandre Biton's 1969 grammar and French-Ndumu dictionary produced for religious and linguistic purposes. Missions operated in the Haut-Ogooué region beginning in the 1840s, and Ndumu's historical status as the language of missions and intertribal communication suggests significant church engagement. This partial audio Scripture project by Hosanna and CIEATLG (Coordination Inter-Eglises pour la Traduction et l'alphabetisation en Langue Gabonaise) addresses the needs of oral and audio learners in a community where formal literacy in Ndumu is minimal and French-language education dominates institutional life. By providing Scripture in audio format, the project enables indigenous Bandumu church leaders to disciple believers, conduct worship, and evangelize in the heart language, preserving the spiritual vitality of a language community facing urbanization and generational language loss.
