Genesis 2:18-22

18And the LORD God said, It is not good that the man should be alone; I will make him an help meet for him.1 19And out of the ground the LORD God formed every beast of the field, and every fowl of the air; and brought them to Adam to see what he would call them: and whatever Adam called every living creature, that was its name.2 20And Adam gave names to all cattle, and to the fowls of the air, and to every beast of the field; but for Adam there was not found an help meet for him.3

21And 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 in its place; 22And the rib, which the LORD God had taken from man, he made a woman, and brought her to the man.4
