In the Anselm Project Bible: Across the supplied verses, the APB presents the name as "Jonah," including "the sign of Jonah" and "the preaching of Jonah." Because the APB is a whole-verse translation, these phrases confirm the verse contexts rather than isolate every contribution of the Greek form.
