BBE(i)
43 You are not to make yourselves disgusting with anything which goes about flat on the earth; you may not make yourselves unclean with them, in such a way that you are not holy to me.
44 For I am the Lord your God: for this reason, make and keep yourselves holy, for I am holy; you are not to make yourselves unclean with any sort of thing which goes about flat on the earth.
