'Skirts' in the Bible

Also in thy skirts is found the blood of the souls of the poor innocents: I have not found it by secret search, but upon all these.

And if thou say in thine heart, Wherefore come these things upon me? For the greatness of thine iniquity are thy skirts discovered, and thy heels made bare.

Therefore will I discover thy skirts upon thy face, that thy shame may appear.
