The father of Naarai. Naarai was one of King David's special warriors called "the thirty" (1 Chronicles 11:37). 2 Samuel 23:35 calls him Paarai the Arbite. Some interpreters suggest that "the son of Ezbai" in the 1 Chronicles passage is a corruption of "the Arbite." The correct reading of his name should be "Naarai the Arbite."
