In Gbaya, the notion of something or someone being completely encircled or surrounded is emphasized in the referenced verses with liŋgɔm, an ideophone that expresses the fact of being all around, of completely encircling.

Note in Exodus 14:27, this refers to the sea returning to its normal depth.

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