Divrey Hayamim Alef 11:5-7

Orthodox Jewish Bible

⁵ And the inhabitants of Yevus said to Dovid, Thou shalt not come in here. Nevertheless Dovid took the Metzudat Tziyon, which is Ir Dovid.

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.
