'Nakedness' in the Bible

so doth the king of Asshur lead the captivity of Egypt, and the removal of Cush, young and old, naked and barefoot, with seat uncovered -- the nakedness of Egypt;

Thy nakedness shall be uncovered, yea, thy shame shall be seen: I will take vengeance, and I will not meet thee as a man.

Behind the doors also and the posts hast thou set up thy remembrance: for apart from me, thou hast uncovered thyself, and art gone up; thou hast enlarged thy bed, and hast made agreement with them; thou lovedst their bed, thou sawest their nakedness.
