Tobit 6:10-20

10 And Tobias said to him: Where wilt thou that we lodge?
11 And the angel answering, said: Here is one whose name is Raguel, a near kinsman of thy tribe, and he hath a daughter named Sara, but he hath no son nor any other daughter beside her.
12 All his substance is due to thee, and thou must take her to wife.
13 Ask her therefore of her father, and he will give her thee to wife.
14 Then Tobias answered, and said: I hear that she hath been given to seven husbands, and they all died: moreover I have heard, that a devil killed them.
15 Now I am afraid, lest the same thing should happen to me also: and whereas I am the only child of my parents, I should bring down their old age with sorrow to hell.
16 Then the angel Raphael said to him: Hear me, and I will shew thee who they are, over whom the devil can prevail.
17 For they who in such manner receive matrimony, as to shut out God from themselves, and from their mind, and to give themselves to their lust, as the horse and mule, which have not understanding, over them the devil hath power.
18 But thou when thou shalt take her, go into the chamber, and for three days keep thyself continent from her, and give thyself to nothing else but to prayers with her.
19 And on that night lay the liver of the fish on the fire, and the devil shall be driven away.
20 But the second night thou shalt be admitted into the society of the holy Patriarchs.
