Romans 7:2-4 New Revised Standard Version (NRSV)
2 Thus a married woman is bound by the law to her husband as long as he lives; but if her husband dies, she is discharged from the law concerning the husband. 3 Accordingly, she will be called an adulteress if she lives with another man while her husband is alive. But if her husband dies, she is free from that law, and if she marries another man, she is not an adulteress.
4 In the same way, my friends,[a] you have died to the law through the body of Christ, so that you may belong to another, to him who has been raised from the dead in order that we may bear fruit for God.
