King David had at least eight wives according to the Bible, though the exact number is not definitively known because the Bible mentions he took more wives after arriving in Jerusalem, whose names are not given. The eight named wives are Michal, Ahinoam of Jezreel, Abigail, Maacah (daughter of Talmai, king of Geshur), Haggith, Abital, Eglah, and Bathsheba

. Additionally, David had concubines, with at least ten mentioned in the scriptures, further increasing the number of women associated with him

. Some sources mention six wives during his time in Hebron, but the broader biblical record supports at least eight named wives and possibly more unnamed ones

. In summary:

• Named wives: 8 (Michal, Ahinoam, Abigail, Maacah, Haggith, Abital, Eglah, Bathsheba)
• Additional unnamed wives after moving to Jerusalem
• At least 10 concubines

This reflects the biblical record that David did not adhere strictly to the command in Deuteronomy 17:17, which forbids kings from taking many wives
