The king and his men went to Jerusalem;
the Jebusites spoke to David, saying,  
     "You shall not come in here, 
   the blind and the lame will repel you.     
   David cannot come in here." 

Nevertheless David took the stronghold
        of Zion (Jerusalem);  

    and said on that day,
    "Whoever climbs up by way of the water 
shaft 
    and defeats the Jebusites,
    shall be chief and captain."

Then David dwelt in the stronghold,
    and called it the City 
of David.  
So David went on and became great,
    and the 
Lord God of hosts was with him.
