King James Bible
"And Lamech took unto him two wives: the name of the one was Adah, and the name of the other Zillah."
This marks the first recorded instance of polygamy in Scripture, departing from God's original design of one man and one woman in Genesis 2:24. Lamech, a descendant of Cain, introduces this practice as part of the moral decline in Cain's lineage. The specific naming of both wives emphasizes the historical reality of this account and sets up the genealogical record that follows. Their names (Adah meaning 'ornament' and Zillah meaning 'shade') suggest they were valued possessions rather than equal partners.
