🔼The name Paltite in the Bible
The name Paltite occurs only once in the Bible. In 2 Samuel 23:26 we learn about Helez the Paltite, who was counted among the mighty-men of David. In the mighty-man list of the Chronicler, however, this Helez is called a Pelonite (1 Chronicles 11:27).
The ethnonym Paltite might point to the name of a city named פלט (Palat or Pelet, or something like that), and the only Biblical name that comes close to that is Beth-pelet in Judah (Joshua 15:27). But it could also be that Paltite indicates a descendant of a sub-clan's patriarch named Pelet (of which there are two mentioned in the Bible). That would explain why in the Book of Samuel Helez is called a Paltite (= someone of the family of Pelet), and in Chronicles a Pelonite (= someone from a town called Pelon).
