2 Samuel 5:5-6

5In Hebron he reigned over Judah seven years and six months, and in Jerusalem he reigned 33 years over all Israel and Judah.

6Now the king and his soldiers marched to Jerusalem against the Jebusites, the inhabitants of the region. But they said to David, “You’ll never get in here! Even the blind and the lame could ward you off,” thinking, “David can’t get in here.”
