Genesis 39:1-2, 6-12, 16-20a (NIV)
1 Now Joseph had been taken down to Egypt. Potiphar, an Egyptian who was one of Pharaoh’s officials, the captain of the guard, bought him from the Ishmaelites who had taken him there.
2 The Lord was with Joseph so that he prospered, and he lived in the house of his Egyptian master.
6a So Potiphar left everything he had in Joseph’s care; with Joseph in charge, he did not concern himself with anything except the food he ate.
6b Now Joseph was well-built and handsome, 7 and after a while his master’s wife took notice of Joseph and said, “Come to bed with me!”
8 But he refused. “With me in charge,” he told her, “my master does not concern himself with anything in the house; everything he owns he has entrusted to my care. 9 No one is greater in this house than I am. My master has withheld nothing from me except you, because you are his wife. How then could I do such a wicked thing and sin against God?”
10 And though she spoke to Joseph day after day, he refused to go to bed with her or even be with her.
11 One day he went into the house to attend to his duties, and none of the household servants was inside. 12 She caught him by his cloak and said, “Come to bed with me!” But he left his cloak in her hand and ran out of the house.
16 She kept his cloak beside her until his master came home. 17 Then she told him this story: “That Hebrew slave you brought us came to me to make sport of me. 18 But as soon as I screamed for help, he left his cloak beside me and ran out of the house.”
19 When his master heard the story his wife told him, saying, “This is how your slave treated me,” he burned with anger. 20a Joseph’s master took him and put him in prison, the place where the king’s prisoners were confined.
