2 Samuel 5:6 KJV

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

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

6And the king and his men went to Jerusalem unto the Jebusites, the inhabitants of the land: which spake unto David, saying, Except thou take away the blind and the lame, thou shalt not come in hither: thinking, David cannot come in hither.

7Nevertheless David took the strong hold of Zion: the same is the city of David.

8And David said on that day, Whosoever getteth up to the gutter, and smiteth the Jebusites, and the lame and the blind, that are hated of David’s soul, he shall be chief and captain. Wherefore they said, The blind and the lame shall not come into the house.
