tsiv.y.yah is a personal name used for the woman identified as Joash’s mother.

The attested form is used as a personal name: 2 Chronicles 24:1 identifies its bearer as Joash’s mother, while 2 Kings 12:2 contains the same form although the APB does not reproduce the name in its translation.

   In 2 Chronicles 24:1, the form is tagged as a proper noun and occurs in the statement naming Joash’s mother; the APB renders, “His mother's name was Zibiah; she was from Beersheba.” The same proper-noun form occurs in 2 Kings 12:2, but the APB translation instead reports Jehoash’s upright conduct and does not visibly reproduce the name.

In the Anselm Project Bible: In 2 Chronicles 24:1, the APB explicitly gives the name as “Zibiah.” In 2 Kings 12:2, the supplied translation does not visibly reflect the proper name, so its specific rendering cannot be isolated from the APB text.
