Tobit 6:12

12 And the maid is fair and wise: now therefore hear me, and I will speak to her father; and when we return from Rages we will celebrate the marriage: for I know that Raguel cannot marry her to another according to the law of Moses, but he shall be guilty of death, because the right of inheritance doth rather appertain to thee than to any other.

Tobit 6:12 In-Context

10 The angel said to the young man, Brother, to day we shall lodge with Raguel, who is thy cousin; he also hath one only daughter, named Sara; I will speak for her, that she may be given thee for a wife.
11 For to thee doth the right of her appertain, seeing thou only art of her kindred.
12 And the maid is fair and wise: now therefore hear me, and I will speak to her father; and when we return from Rages we will celebrate the marriage: for I know that Raguel cannot marry her to another according to the law of Moses, but he shall be guilty of death, because the right of inheritance doth rather appertain to thee than to any other.
13 Then the young man answered the angel, I have heard, brother Azarias that this maid hath been given to seven men, who all died in the marriage chamber.
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 other before: for a wicked spirit loveth her, which hurteth no body, but those which come unto her; wherefore 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.
