Genesis 2

18 The LORD God also said, "It is not good for the man to be alone. I will make for him a suitable helper."

19 And out of the ground the LORD God formed every beast of the field and every bird of the air, and He brought them to the man to see what he would name each one. And whatever the man called each living creature, that was its name. 20 The man gave names to all the livestock, to the birds of the air, and to every beast of the field. But for Adam*2:20 Or the man, as in verses 19 and 21 no suitable helper was found.

21 So the LORD God caused the man to fall into a deep sleep, and while he slept, He took one of the man’s ribs*2:21 Or took part of the man’s side; similarly in verse 22 and closed up the area with flesh. 22 And from the rib that the LORD God had taken from the man, He made a woman and brought her to him. 23 And the man said:

"This is now bone of my bones

and flesh of my flesh;

she shall be called ‘woman,’

for out of man she was taken."

24 For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh.*2:24 LXX and the two will become one flesh; cited in Matthew 19:5, Mark 10:7–8, 1 Corinthians 6:16, and Ephesians 5:31
