Saul disguised himself by putting on different clothes. Then, taking
two men with him, he went under the cover of night to the woman and
said, "I want you to consult a ghost for me. Call up the person I name." I Samuel 28:8 (TM)

Isn’t it funny how we try to hide, or disguise ourselves when we’re doing something we know we shouldn’t? Just the fact that we don’t want to be seen should give us a clue, shouldn’t it?
