Questions about Cain’s wife are often asked by Bible students and frequently used by religious skeptics who seek to discredit the reliability of the Bible.

Clarence Darrow, ALCU lawyer in the infamous 1925 Scopes trial in Tennessee, asked about Cain’s wife. When William Jennings Bryan, seen as a representative of Bible believers at the trial, failed to provide a suitable answer, the media portrayed Christians as unable to defend the biblical text. This caricature persists. Prominent atheist Carl Sagan’s 1985 bestseller Contact assigned the question about Cain’s wife a prominent role in bringing disillusionment to a fictional professing Christian. Again, the real target was the integrity and reliability of Scripture.

Do we have an adequate answer? The Bible does not answer the question directly, but provides ample information for us to draw a solid conclusion. All people are descended from Adam and Eve (Genesis 3:20; Acts 17:26), who had many children aside from Cain, Abel, and Seth (Genesis 5:4). Genesis 4 does not give us a complete listing of all of Adam and Eve’s children or a full account of everything that happened during their lifetime. It stresses those people and events that are pertinent to the purpose of the book of Genesis. As is common throughout Scripture, we are given selective snapshots of purposefully chosen people for the presentation of law and gospel in the course of history.
