🔼The name Bor-ashan in the Bible
It's not clear whether Bor-ashan is supposed to be a Biblical name or not. If it is, then it occurs in 1 Samuel 30:30, where it is listed as one of the Judean cities that received gifts from David, taken from the band of Amalekites who had raided David's headquarter in Ziklag.
The problem is that some Hebrew manuscripts read Chor-ashen (כור עשן; note that the Hebrew letters ב (beth) and כ (kaph) are somewhat similar), the Septuagint reads Βηρσαβεε (Bersabee, which would be the same as Beersheba if the Septuagint hadn't translated that name instead of transliterate it), and the Vulgate skips this name altogether and speaks of "the lake Asan". In English, the older translations speak of Chor-ashan or Chorashan (King James, Darby, Young) but younger versions prefer Bor-ashan or Bor Ashan (ASV, NAS, NIV, JSP).
Most scholars assume that Bor-ashan or Chor-ashan is the same city as the one in Judah simply called Ashan (Joshua 15:42).
