Sotah 12a says that Azubah is Miriam.
When I looked up I Chronicles 2:19 ( pic below ) , it said, 'And Azubah died, and Caleb took to himself Ephrath, and she bore him Hur'.
It seems from what I read in I Chronicles 2:19, Azubah and Ephrath cannot be the same women according to I Chronicles 2:19; unless you give an entire new meaning to the word, 'died' in I Chronicles 2:19.
( Ephrath is AKA Miriam. I am not providing a source for this cause it is accepted by all) .
So are the 2 names Azubah and Miram talking about the same person or not?
Is it possible that Azubah was actually Bitya, Moshe Rabbeinu's adoptive mother who was also the daughter of Pharaoh? I say this because in I Chronicles 4:18, Rashi talks about '...the sons of Bithiah the daughter of Pharaoh, whom Mered married. ( Mered being Caleb according to Rashi).
More indication that Azubah was not Miriam can be found in the pic below whose Ref is: I Chronicles 2:18
