 By 2001 Berveling had also translated to Esperanto and published three volumes of the Deuterocanonical books ("La duakanonaj libroj").Texts from the first two volumes, as used in the Orthodox, Roman Catholic and Lutheran churches, were incorporated into an edition of the Esperanto Bible published two years later.In 2006 the ecumenical commission of the International Union of Catholic Esperantists (IKUE) and the International Christian Esperantist League (KELI) edited a completely new arrangement of the Bible based on the Latin Vulgate edition, which was published by Kava-Pech in the Czech Republic and now forms a volume in the World Esperanto Association's "Serio Oriento-Okcidento" ("East-West Series"), a series of some 50 works published in uniform editions, initially as a contribution to UNESCO's Major Project on Mutual Appreciation of Eastern and Western Cultural Values.
