D&C 132:54-56; “And I command mine handmaid, Emma Smith, to abide and cleave unto my servant Joseph, and to none else. But if she will not abide this commandment she shall be destroyed, saith the Lord; for I am the Lord thy God, and will destroy her if she abide not in my law. But if she will not abide this commandment, then shall my servant Joseph do all things for her, even as he hath said; and I will bless him and multiply him and give unto him an hundredfold in this world, of fathers and mothers, brothers and sisters, houses and lands, wives and children, and crowns of eternal lives in the eternal worlds. And again, verily I say, let mine handmaid forgive my servant Joseph his trespasses; and then shall she be forgiven her trespasses, wherein she has trespassed against me; and I, the Lord thy God, will bless her, and multiply her, and make her heart to rejoice.”
1 Cor. 7:8-9; “I say therefore to the unmarried and widows, It is good for them if they abide even as I. 9But if they cannot contain, let them marry: for it is better to marry than to burn.”
