🔼The name Caleb-ephrathah in the Bible
The name Caleb-ephrathah occurs only one time in the Bible. It's the place where Hezron, the father of Caleb (not the famous one), passed away (1 Chronicles 2:24). Caleb's wife was named Ephrath, and it's reasonable to assume that our town was named after them.
It may be that Caleb-ephrathah is the same as Bethlehem-ephrathah (Micah 5:2), and later just Bethlehem of Judah, as Alfred Jones (Dictionary of Old Testament Proper Names) dictates, but there's little evidence for that.
