🔼The name Aziza in the Bible
The name Aziza occurs only one time in the Bible. During Ezra's restoration of Jerusalem and subsequently obedience to the Law of YHWH, a large group of men divorce their foreign wives and their children. Among the sons of Zattu, Ezra mentions a man named Aziza.
It should be noted that God hates divorce for any reason (Malachi 2:16), and even though international marriages were forbidden by God (Deuteronomy 7:3), there are notable exceptions (such as Boaz' marriage to Ruth, the Moabite ancestor of king David and Jesus Christ) and this bizarre mass divorce was not ordered by God; it was the Israelites' own idea (Ezra 10:2-3, 10-11).
Four men, Jonathan son of Asahel, Jahzeiah son of Tikvah, and Meshullam and Shabbethai, oppose the plan, but the exiles won't change their mind and stand shuddering in the pelting rain, figuring they're doing something lofty. Whatever became of the wives and the children after this connubial carnage is unknown.
🔼Etymology of the name Aziza
The name Aziza comes from the verb עזז ('azaz), meaning to be strong:
It's not immediately clear what the added aleph is doing at the end of the name, but it may simply be a playful (Aramaic) addition that doesn't change the conveyed meaning.
For a meaning of the name Aziza, both Jones' Dictionary of Old Testament Proper Names and NOBSE Study Bible Name List read Strong. BDB Theological Dictionary does not translate.
