In Gbaya, the notion of being quiet or moving slowly is emphasized in the referenced verses with the ideophone gɛ́ɗɛ́k. (Note that in Jeremiah 27:11 “leave on its own land” is interpreted as “leave in peace on its own land,” in Jeremiah 49:31 “lives alone” as being “apart from others [and therefore quietly].”)

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