The City of David
“And the king and his men went to Jerusalem against the Jebusites, the inhabitants of the land, who spoke unto David, saying: 'Except thou take away the blind and the lame, thou shalt not come in hither'; thinking: 'David cannot come in hither.'
Nevertheless David took the stronghold of Zion; the same is the city of David.
And David said on that day: 'Whosoever smiteth the Jebusites, and getteth up to the gutter, and [taketh away] the lame and the blind, that are hated of David's soul--.' Wherefore they say:
'There are the blind and the lame; he cannot come into the house.'
And David dwelt in the stronghold, and called it the city of David. And David built round about from Millo and inward.”
2 Samuel 5:6-9
