Tobit 6:16

16 And when thou shalt come into the marriage chamber, thou shalt take the ashes of perfume, and shalt lay upon them some of the heart and liver of the fish, and shalt make a smoke with it.

Tobit 6:16 In-Context

14 And now I am the only son of my father; and I am afraid lest, if I go in unto her, I die, as the others before. For a wicked spirit loveth her, which hurteth nobody but those who come unto her. Therefore I also fear, lest I die and bring my father's and my mother's life, because of me, to the grave with sorrow; for they have no other son to bury them."

15 Then the angel said unto him, "Dost thou not remember the precepts which thy father gave thee, that thou shouldest marry a wife of thine own kindred? Therefore hear me, O my brother, for she shall be given thee for a wife; and take thou no account of the evil spirit, for this same night shall she be given thee in marriage.

16 And when thou shalt come into the marriage chamber, thou shalt take the ashes of perfume, and shalt lay upon them some of the heart and liver of the fish, and shalt make a smoke with it.

17 And the devil shall smell it, and flee away, and never come again any more. But when thou shalt come to her, rise up both of you, and pray to God who is merciful, who will have pity on you and save you. Fear not, for she is appointed unto thee from the beginning; and thou shalt preserve her, and she shall go with thee. Moreover I suppose that she shall bear thee children." Now when Tobias had heard these things, he loved her, and his heart was effectually joined to her.
