1 Chronicles 8:18 lists three men—Ιshmerai, Jezliah, and Jobab—who are identified as sons of Elpaal. This verse is part of a genealogical record, simply naming these individuals as descendants within a particular family line.
This verse appears in a section where the writer is carefully tracing the lineage of the tribe of Benjamin. The chronicler is listing out the descendants for historical and tribal record-keeping, showing the family connections and preserving the names of those who belonged to this line. There is no story or event described here, just a factual record of ancestry.
