Consequences Of Having Another's Spouse

Genesis 12:17-20

17  And the LORD plagued Pharaoh and his house with great plagues because of Sarai Abram's wife. 
18  And Pharaoh called Abram, and said, What is this that thou hast done unto me? why didst thou not tell me that she was thy wife? 
19  Why saidst thou, She is my sister? so I might have taken her to me to wife: now therefore behold thy wife, take her, and go thy way. 
20  And Pharaoh commanded his men concerning him: and they sent him away, and his wife, and all that he had.
