Tobit 8:6-8

New Revised Standard Version Catholic Edition

⁶ You made Adam, and for him you made his wife Eve
    as a helper and support.
    From the two of them the human race has sprung.
You said, ‘It is not good that the man should be alone;
    let us make a helper for him like himself.’
⁷ 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.”
