'Legs' in the Bible

Then the Jews, because it was the day of preparation, so that the bodies would not remain on the cross on the Sabbath (for that Sabbath was a high day), asked Pilate that their legs might be broken, and that they might be taken away.

So the soldiers came, and broke the legs of the first man and of the other who was crucified with Him;

but coming to Jesus, when they saw that He was already dead, they did not break His legs.
