The answer to the question “Who was Cain’s wife?” is unknown from the biblical text. The Bible does not name Cain’s wife, and it is assumed that she was either a relative of his or a woman that he met while traveling.
The story of Cain and Abel, as told in Genesis 4, revolves around the brothers who were first born to Adam and Eve. Cain was the firstborn son, and Abel was the younger brother. Both brothers offered sacrifices to God, but only Abel’s sacrifice was accepted by God. Cain became jealous of Abel and ultimately murdered him.
The Bible does mention other places where Cain could have found a wife, such as “the land of Nod”. This suggests that Cain traveled to another area where he met someone, or that he found a relative to marry. Some suggest that since Adam and Eve had many children, Cain may have married one of his siblings. Others think Cain either married an unrelated woman living in the land of Nod or a descendant of Adam and Eve’s third son, Seth.
Regardless of who his wife was, it is clear that marriage was a part of God’s plan for humanity even during the time of Cain and Abel. Marriage is a beautiful reflection of God’s grace and love and continues to be an important part of Christian life today.
