In Gbaya, the notion of complete fullness is emphasized in the referenced verses with with gbol-gbol, an ideophone that describes a state of complete fullness or as of a container being filled to the brim.

Note that in Psalm 83:5 it refers to everyone being fully in unison.

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