이러므로 남자가 부모를 떠나 그 아내와 연합하여 둘이 한 몸을 이룰지로다
Allegorical Interpretation of Genesis
[49] “For this cause shall a man leave his father and his mother, and shall cleave unto his wife, and the twain shall be one flesh” (Gen. 2:24). For the sake of sense-perception the Mind, when it has become her slave, abandons both God the Father of the universe, and God’s excellence and wisdom, the Mother of all things, and cleaves to and becomes one with sense-perception and is resolved into sense-perception so that the two become one flesh and one experience.
On the Giants
[65] But the sons of earth have turned the steps of the mind out of the path of reason and transmuted it into the lifeless and inert nature of the flesh. For “the two became one flesh” as says the lawgiver (Gen. 2:24). Thus they have debased the coin of truest metal and deserted from their post, left a place that was better for a worse, a place amid their own people for a place amid their foes. It was Nimrod who began this desertion.
The Midrash of Philo
Why he says, "Therefore shall a man leave his father and his mother, and cleave to his wife, and they shall be two in one flesh?" (Genesis 2:24).
