Tob 8, 4-9 I take this wife of mine for a noble purpose

(Tob 8, 4-9) I take this wife of mine for a noble purpose

[4] When the girl's parents left the bedroom and closed the door behind them, Tobiah arose from bed and said to his wife, "My love, get up. Let us pray and beg our Lord to have mercy on us and to grant us deliverance." [5] She got up, and they started to pray and beg that deliverance might be theirs. He began with these words: "Blessed are you, O God of our fathers; praised be your name forever and ever. Let the heavens and all your creation praise you forever. [6] You made Adam and you gave him his wife Eve to be his help and support; and from these two the human race descended. You said, 'It is not good for the man to be alone; let us make him a partner like himself.' [7] Now, Lord, you know that I take this wife of mine not because of lust, but for a noble purpose. Call down your mercy on me and on her, and allow us to live together to a happy old age." [8] They said together, "Amen, amen," [9] and went to bed for the night.

(CCC 2361) "Sexuality, by means of which man and woman give themselves to one another through the acts which are proper and exclusive to spouses, is not something simply biological, but concerns the innermost being of the human person as such. It is realized in a truly human way only if it is an integral part of the love by which a man and woman commit themselves totally to one another until death" (FC 11). Tobias got out of bed and said to Sarah, "Sister, get up, and let us pray and implore our Lord that he grant us mercy and safety." So she got up, and they began to pray and implore that they might be kept safe. Tobias began by saying, "Blessed are you, O God of our fathers.... You made Adam, and for him you made his wife Eve as a helper and support. From the two of them the race of mankind has sprung. You said, 'It is not good that the man should be alone; let us make a helper for him like himself.' I now am taking this kinswoman of mine, not because of lust, but with sincerity. Grant that she and I may find mercy and that we may grow old together." and they both said, "Amen, Amen." Then they went to sleep for the night (Tob 8:4-9).
