Genesis 2:23-25

Then Adam said, “This is now bone of my bones, And flesh of my flesh; She shall be called Woman, Because she was taken out of Man.” For this reason a man shall leave his father and his mother, and shall be joined to his wife; and they shall become one flesh. [Matt 19:5; 1 Cor 6:16; Eph 5:31-33] And the man and his wife were both naked and were not ashamed or embarrassed.
