2 Samuel 5:5 WEB

³  So all the elders of Israel came to the king to Hebron; and king David made a covenant with them in Hebron before Yahweh: and they anointed David king over Israel.

⁴  David was thirty years old when he began to reign, and he reigned forty years.

⁵  In Hebron he reigned over Judah seven years and six months; and in Jerusalem he reigned thirty-three years over all Israel and Judah.

⁶  The king and his men went to Jerusalem against the Jebusites, the inhabitants of the land, who spoke to David, saying, Except you take away the blind and the lame, you shall not come in here; thinking, David can't come in here.

⁷  Nevertheless David took the stronghold of Zion; the same is the city of David.
