“And the Lord God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof; And the rib, which the Lord God had taken from man, made he a woman, and brought her unto the man. And 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. Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.” – Genesis 2: 21-24
“Set me as a seal upon your heart, as a seal upon your arm; for love is as strong as death, jealousy as cruel as the grave; its flames are flames of fire, a most vehement flame. Many waters cannot quench love, nor can the floods drown it. If a man would give for love, all the wealth of his house, it would be utterly despised.” – Song of Solomon 8: 6-7
“For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church.” – Ephesians 5: 29
