1 Corinthians 7:39–40: Can a Widow Remarry?
Paul tells the Corinthian church that death ends the marriage bond, so a widow is free to marry anyone, provided the marriage is in the Lord. He then gives his own judgment that she would be happier to remain as she is.
Matthew 19:3–9: Is Divorce a Sin?
Jesus refuses to start with grounds for divorce and instead starts with God's making of male and female and the joining of two into one flesh. He names one exception, sexual immorality, and treats the Mosaic allowance as a concession to hard hearts rather than the original design.
Matthew 19:3–9: Is Divorce a Sin?
Jesus does not answer the divorce question with a list of loopholes. He goes behind Moses' permission to God's purpose in creation, then names hard hearts and one exception.
