Lamech took two wives It was one of the degenerate race of Cain who first transgressed the original law of marriage, that two only should be one flesh, and introduced a custom which still subsists in many parts of the world. Christ fully laid open the iniquity of this practice, and restored marriage to its first form, Matthew 19:8.
