In Gbaya, the notion of tears that flow without ceasing in Lamentations 3:49 is emphasized with vamgba-vamgba, an ideophone that designates the flow of a liquid that never dries up like inexhaustible tears.
Ideophones are a class of sound symbolic words expressing human sensation that are used as literary devices in many African languages. (Source: Philip Noss)
