Writing prophetic oracles in a consonantal alphabet as was Hebrew or Aramaic at the time of ancient Israel, in the first millennium BCE, is not without asking questions and in particular the following: how to ensure the correct transcription and transmission of a prophetic writing? Can the singing, screaming or crying of the prophetic performance be transcribed? These are all the more important in a prophetic context where it is about revealing divine words. What tools, practices or techniques do ancient texts, which were neither vocalized nor accentuated –this will be the work of the Masoretes in medieval times – reveal to ensure the correct transcription, reading and understanding of an oracle? This is the investigation that we propose in this issue, dedicated to speech in its sound dimension and in its relationship to writing, through three main witnesses: Dan 5, Isa 8 and Jer 1.
