Genesis 1:27; 2:5-7, 18, 21-24

1:27 So God created man in his own image,
    in the image of God he created him;
    male and female he created them.…

2:5 When no bush of the field was yet in the land and no small plant of the field had yet sprung up—for the Lord God had not caused it to rain on the land, and there was no man to work the ground, 6 and a mist was going up from the land and was watering the whole face of the ground— 7 then the Lord God formed the man of dust from the ground and breathed into his nostrils the breath of life, and the man became a living creature. …

18 Then the Lord God said, “It is not good that the man should be alone; I will make him a helper fit for him.” …

21 So the Lord God caused a deep sleep to fall upon the man, and while he slept took one of his ribs and closed up its place with flesh. 22 And the rib that the LordGod had taken from the man he made into a woman and brought her to the man.23 Then the man said,

“This at last is bone of my bones
    and flesh of my flesh;
she shall be called Woman,
    because she was taken out of Man.”

24 Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.
