What does Genesis 2:24 really mean?

The Bible's first definition of marriage — not a social custom but a creational pattern woven into the fabric of humanity itself.

KJV

Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.

BSB

For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh.

The plain meaning

This verse arrives immediately after Adam recognizes Eve as "bone of my bones, and flesh of my flesh" (v. 23). The logic is tight: because the woman was taken from the man, a man leaving his parental household to form a new, singular bond with his wife is the natural response to what marriage actually is. Three verbs carry the weight — leave, cleave, become one flesh — and they move in sequence: departure, devoted attachment, and a union so complete that two people constitute a single social and physical reality. Jesus quotes this verse directly in Matthew 19:4–5, tracing it to the Creator's intent "from the beginning," and Paul invokes it in Ephesians 5:31 as the template for understanding Christ's relationship to the church. The verse is not situational advice for the ancient Near East. It is the founding charter of marriage as an institution — prior to Sinai, prior to Israel, rooted in how human beings were made.

The common misreading

"One flesh" is primarily about sex. The phrase gets reduced to its physical dimension — as if the verse is simply a poetic way of saying the couple will sleep together. But the sequence of the three verbs matters: first the man leaves his prior household (a social, legal realignment), then he cleaves to his wife (covenantal loyalty and devotion), and only then are they described as one flesh. 'One flesh' in Hebrew thought encompasses the full unity of two persons — shared life, shared interests, shared identity — not just a physical act. Paul confirms this when he quotes the verse in Ephesians 5:31 as an image of Christ's total self-giving to the church, which is obviously not a sexual metaphor. Adam Clarke makes the point plainly: the two become one body with no separate or independent rights, privileges, or concerns. The physical union is real and included, but it is the sign of a comprehensive oneness, not the whole of it.

What the commentators say

Adam Clarkeearly 19th c. · PD

Clarke emphasizes that the marital bond God establishes here is more intimate than even the parent-child relationship — not a lesser loyalty but a different and deeper one. He also argues that the word 'two' (present in the New Testament quotations and the Septuagint) was likely original to the Hebrew, and its presence decisively restricts lawful marriage to one man and one woman at a time, closing the door on polygamy.

John Gill18th c. · PD

Gill reads these as the words of God himself instituting marriage — not merely Moses commenting or Adam guessing — a reading confirmed by how Jesus prefaces the same words in Matthew 19:5 ('he that made them... said'). Gill stresses that 'cleave' pictures a gluing-together, two people made one body so thoroughly that the text stands as a direct refutation of polygamy, unlawful divorce, and sexual immorality of every kind.

Jamieson, Fausset & Brown19th c. · PD

JFB notes that what makes this human pair unique among all pairs is that Eve's formation from Adam meant they were already one before the institution was declared. The verse is then taken up by both Christ (Matthew 19:4–5) and Paul (Ephesians 5:28–31) as the definitive divine blueprint for marriage, giving it a weight that transcends culture or era.

The word behind it

דָּבַק davaq

'Cleave' — to cling, adhere, or be glued to. The same verb is used in Ruth 1:14 when Ruth 'clung' to Naomi and in Deuteronomy 10:20 when Israel is commanded to 'hold fast' to God. It is not a mild fondness; it is tenacious, covenantal attachment. The word rules out the idea that marriage is a temporary or provisional arrangement — it describes a bond that by its nature resists separation.
