i mean if youre really looking at the text this closely:

May have been the third wife: from Genesis 1:

27 So God created mankind in his own image,
in the image of God he created them;
male and female he created them.

28 God blessed them and said to them, “Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish in the sea and the birds in the sky and over every living creature that moves on the ground.”

........

31 God saw all that he had made, and it was very good. And there was evening, and there was morning—the sixth day.

Chronologically speaking, God had already created a female human. For some reason he had to take a rib from Adam for the subsequent woman.
