2 Samuel 5:5-6

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

6The king and his men marched to Jerusalem to attack the Jebusites, who lived there. The Jebusites said to David, “You will not get in here; even the blind and the lame can ward you off.” They thought, “David cannot get in here.”
