In Gbaya, the notion of the falling snow in Sirach 43:13 is emphasized with mbul-mbul, an ideophone that refers to something that falls very finely. Note that the Gbaya translators interpreted along the lines of the French Traduction œcuménique de la Bible which has “causes snow to fall” (il précipite la neige).

Ideophones are a class of sound symbolic words expressing human sensation that are used as literary devices in many African languages. (Source: Philip Noss)
