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 African languages. (Source: Philip Noss)
