Potiphar's wife looks at Joseph. Day after day she invites him to lie with her. Day after day he refuses. He will not betray Potiphar, who has trusted him with everything in the house — "he has withheld nothing from me except you, because you are his wife." And then, in the most direct theological statement in Joseph's story: "How can I do this great wickedness and sin against God?"
One day she catches his garment as he flees. He leaves it in her hand and runs. She calls the household servants and tells them Joseph attacked her. When Potiphar comes home, she tells him again. His anger burns. Joseph is thrown into prison.
The second stripping. The coat taken in the field. The garment taken in the house. Joseph goes down again.
