“¶ And the king and his men went to Ierusalem, vnto the Iebusites, the inhabitants of the land: which spake vnto Dauid, saying, Except thou take away the blind and the lame, thou shalt not come in hither: Thinking, Dauid cannot come in hither.”
1611 King James Version (KJV)
5:6 Cannot come - They confided in the strength of their fortifications, which they thought so impregnable, that the blind and the lame were sufficient to defend them, against the most powerful assailant. And probably they set a parcel of blind and lame people, invalids or maimed soldiers, to make their appearance on the wall, in contempt of David and his men.
