2 Samuel 5:4-6

New Century Version

⁴ David was thirty years old when he became king, and he ruled forty years. ⁵ He was king over Judah in Hebron for seven years and six months, and he was king over all Israel and Judah in Jerusalem for thirty-three years.

⁶ When the king and his men went to Jerusalem to attack the Jebusites who lived there, the Jebusites said to David, “You can’t get inside our city. Even the blind and the crippled can stop you.” They thought David could not enter their city.
