Divrey Hayamim Alef 11:6-8

Orthodox Jewish Bible

⁶ And Dovid said, Whosoever attacketh the Yevusi barishonah shall be Rosh and Sar. So Yoav Ben Tzeruyah went up first, and became Rosh.

⁷ And Dovid dwelt in the Metzad; therefore they called it Ir Dovid.

⁸ And he built the Ir around it, even from the Millo to the surrounding area, and Yoav repaired the rest of the Ir.
