Charles Ellicott Commentary 2 Samuel 23:35

"Hezro the Carmelite, Paarai the Arbite," — 2 Samuel 23:35 (ASV)

Hezrai. —According to the Hebrew margin; but the text has Hezro, as in Chronicles. He was from Carmel, seven miles south-southeast of Hebron, famous in David’s early history.

Paarai the Arbite. —In Chronicles: Naarai the son of Ezbai. It is impossible to decide whether Paarai or Naarai is the correct form, but the son of Ezbai is evidently a scribe’s error for the Arbite, which it must have resembled in the original text.
