Tobit 6:14

14 Now I am the only son my father has, and I am afraid that if I go in I will die as those before me did, for a demon is in love with her, and he harms no one except those who approach her. So now I fear that I may die and bring the lives of my father and mother to the grave in sorrow on my account. And they have no other son to bury them."

Tobit 6:14 In-Context

12 The girl is also beautiful and sensible. Now listen to my plan. I will speak to her father, and as soon as we return from Rages we will celebrate the marriage. For I know that Raguel, according to the law of Moses, cannot give her to another man without incurring the penalty of death, because you rather than any other man are entitled to the inheritance."

13 Then the young man said to the angel, "Brother Azarias, I have heard that the girl has been given to seven husbands and that each died in the bridal chamber.

14 Now I am the only son my father has, and I am afraid that if I go in I will die as those before me did, for a demon is in love with her, and he harms no one except those who approach her. So now I fear that I may die and bring the lives of my father and mother to the grave in sorrow on my account. And they have no other son to bury them."

15 But the angel said to him, "Do you not remember the words with which your father commanded you to take a wife from among your own people? Now listen to me, brother, for she will become your wife; and do not worry about the demon, for this very night she will be given to you in marriage.

16 When you enter the bridal chamber, you shall take live ashes of incense and lay upon them some of the heart and liver of the fish so as to make a smoke.
