Tobit 6:7-17

7 The angel answered, "The heart and liver can be burned and used to chase away a demon or an evil spirit that is tormenting someone. The attacks will stop immediately, and the person will never be troubled again.
8 You can use the gall bladder to treat someone whose eyes are covered with a white film. Just rub it on his eyes and blow on the film, and he will be able to see again."
9 When they had reached Media and were approaching the city of Ecbatana,
10 Raphael said, "Tobias, my friend." "Yes, what is it?" Tobias asked. Raphael continued, "Tonight we will stay at the home of your relative Raguel. He has only one child, a daughter named Sarah,
11 and since you are her closest relative, you have the right to marry her. You also have the right to inherit all her father's property.
12 She is sensible, brave, and very beautiful; and her father is a good man. Tonight I'll discuss the marriage proposal with her father, and he will consent to give her to you as your bride. Then, when we return home from the town of Rages, we will celebrate the marriage. Raguel cannot refuse to let you marry her, and he cannot let any other man have her. If he did, then according to the Law of Moses he would deserve the death penalty. He knows that you are the only man who has the right to marry his daughter and receive the inheritance, so follow my advice. Raguel and I will discuss the matter tonight and arrange your engagement to Sarah. When we get back from the city of Rages, we will take her home with us."
13 Tobias then said to Raphael, "Azarias, my friend, I have already heard about Sarah's seven former husbands, and how each one dropped dead on his wedding night, even before he could get to bed.
14 According to the story I heard, a demon killed them. He doesn't harm Sarah, but he kills every man who tries to get near her. I am afraid of this demon. I am an only child, and if I were to die, the sorrow would send my parents to their graves. They don't even have another son to bury them."
15 The angel replied, "Have you already forgotten your father's instructions? He told you to marry a woman from your own tribe. So, listen carefully to what I say. Don't worry about the demon. Marry Sarah! I know that tonight Raguel will let Sarah marry you.
16 When you go into the bedroom, take the fish's heart and liver with you and place them on the burning incense,
17 so that the odor will spread throughout the room. When the demon smells it, he will leave and never come near Sarah again. But before you consummate the marriage, both of you must get up and pray for the Lord in heaven to be merciful to you and to protect you. Don't be afraid. Sarah was meant to be yours from the beginning of creation. You will rescue her from the demon, and she will go with you to your home. You and Sarah will have many children, whom you will love very much. So don't worry!" Tobias listened very carefully to what Raphael had to say. He knew that Sarah was a relative on his father's side of the family. He began to fall in love with her and looked forward to marrying her.
