New American Bible
As soon as the demon smells the odor, it will flee and never again show itself near her. Then when you are about to have intercourse with her, both of you must first get up to pray. Beg the Lord of heaven that mercy and protection be granted you. Do not be afraid, for she was set apart for you before the world existed. You will save her, and she will go with you. And I assume that you will have children by her, and they will be like brothers for you. So do not worry.” When Tobiah heard Raphael’s words that she was his kinswoman, and of the lineage of his ancestral house, he loved her deeply, and his heart was truly set on her.
