After God created Adam’s first Wife out of Adam’s rib, Adam named her Woman…

Genesis 2:23
“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”

In Hebrew, her name is Ishshah…

Strong's 802: Ishshah
Definition: woman, wife, female

Thus, Adam’s first wife was Ishshah. And from that moment forward, Genesis always refers to her as Ishsha, or as the modern translations would say, Woman.

It is not until Ishshah partakes of the Forbidden Fruit that things begin to change.

After Ishshah ate the Forbidden Fruit, she died. God then had to re-create a second wife for Adam.

Adam named his second wife, Eve…

Genesis 3:20
“And Adam called his wife’s name Eve; because she was the mother of all living”

And there you have it. Eve was Adam’s second wife.
