'Legs' in the Bible

Then the priest will put the oath of the curse on the woman, and say to her, May the Lord make you a curse and an oath among your people, sending on you wasting of the legs and disease of the stomach;

And this water of the curse will go into your body, causing disease of your stomach and wasting of your legs: and the woman will say, So be it.

And it will be that if the woman has become unclean, sinning against her husband, when she has taken the bitter water it will go into her body, causing disease of the stomach and wasting of the legs, and she will be a curse among her people.
