Caleb Ephratah
Fausset's Bible Dictionary [1]
A place where Hezron died. But no such place is named elsewhere; and Hezron died in Egypt, and could hardly have named a place there, nor his son either, both being in bondage there ( 1 Chronicles 2:24). Therefore, the reading in Jerome's Hebrew Bible and in the Septuagint is probably correct, "Caleb came in unto Ephrath" (compare 1 Chronicles 2:19; 1 Chronicles 2:50). Hezron had two wives, the mother of Jerahmeel, Ram, and Caleb or Chelubai; and Abiah, Machir's daughter, whom he married when 60 years old, and who bore him Segub, and posthumously (according to Kjv) Ashur.
Caleb had two wives, Azubah mother of Jerioth (according to Jerome's reading), and Ephrath mother of Hur, this second marriage of Caleb not taking place until after Hezron's death. Others suppose Caleb Ephratah named jointly from husband and wife, and identify it with Bethlehem Ephratah. In Kjv reading, Hezron must be supposed to have died in the place afterward called Caleb Ephratah.
