2 Samuel 5:6
And 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.
Jebus was a fortified stronghold still held by the Canaanites, situated upon the heights of Zion and Moriah. For centuries it had been regarded as impregnable to assault. It was captured by the Hebrews under the leadership of Joab. After its capture it was made the capital of Israel and renamed Jerusalem.
