Genesis 2:22-24

22 Then the Lord God made a woman from the rib he had taken out of the man, and he brought her to the man.

23 The man said,

“This is now bone of my bones
   and flesh of my flesh;
she shall be called ‘woman,’
    for she was taken out of man.”

24 That is why a man leaves his father and mother and is united to his wife, and they become one flesh.

Genesis 2:22-24 beautifully illustrates the creation of woman and the profound bond between husband and wife. In these verses, we find the essence of companionship and unity. The declaration of "bone of my bones and flesh of my flesh" underscores the intimate connection that is established through marriage. It emphasizes that this union is not only physical but also emotional and spiritual, symbolizing the deep relationship that transcends individual identities as they become "one flesh." This passage lays a foundational understanding of marital love and commitment.
