'Body' in the Bible

and underneath the canopy, their wings spread out straight over their heads toward each other. They each also had two wings with which they covered themselves, one wing covering its body on one side and one wing covering itself on the other side.

They are not to come in contact with a dead body, so they don't defile themselves, except in the case of their father, mother, son, daughter, brother, or for an unmarried sister, on whose behalf they may defile themselves.
