'Lame' in the Bible
The king and his men went to Jerusalem, to the Jebusites, the inhabitants of the land. They said to David, "You will not come here, for even the blind and the lame can turn you back, saying, 'David cannot come here.'"
David had said, "On that day {when we attack the Jebusites}, one must attack the lame and the blind, [those] who hate the soul of David, by [means of] the water supply." For thus the blind and the lame would say, "He cannot come into the house."
Then the king said, "But [is] there still anyone of Saul's household that I may show the loyal love of God with him?" And Ziba said to the king, "There [is] still a son of Jonathan [who is] lame in the feet."
And Mephibosheth [was] living in Jerusalem, because he [was] continually eating at the table of the king, [even though] he [was] lame in both of his feet.
Then he said, "My lord the king, my servant deceived me, for your servant had said, 'Let me saddle the donkey that I may ride on her and go with the king,' for your servant [is] lame.
