'Legs' in the Bible

And a certain man who from birth had had no power in his legs, was taken there every day, and put down at the door of the Temple which is named Beautiful, requesting money from those who went into the Temple;

And he took him by his right hand, lifting him up; and straight away his feet and the bones of his legs became strong,

And when Peter saw it he said to the people, You men of Israel, why are you so greatly surprised at this man? or why are you looking at us as if by our power or virtue we had given him the use of his legs?
