In Gen 1:27 it says God created human beings both male and female and blessed them to have many children. Again in Gen 2:18 the Lord says it is not good for man to live alone. I will make a suitable companion to help him. A look at those two verse can say God created a male and female in the first verse and another woman in the second. Did Adam have a first wife?
While the placement of these verses may lead one to believe there were two women created for Adam, one must ask, to what purpose would God create a wife before Eve, and WHY is she never mentioned in scripture again? If another woman was created for Adam, how was she created? Did God take two ribs from Adam when the scriptures say that God takes only one? Did she have children?
Of course, none of us were present during creation so we can only go by what we are told in scripture. Since there is nothing else mentioned about another wife and family, most Bible scholars agree that Genesis 2 (beginning with verse 4) is a recap of the creative process. It gives more specific information about the very special creation of man. God loves and greatly values mankind. Remember what David wrote about man in Psalm 8:4-9, “What is man that you are mindful of him, and the son of man that you care for him? You made him a little lower than the angels and crowned him with glory and honor. You made him ruler over the works of your hands; you put everything under his feet: all flocks and herds and the beasts of the field, the birds of the air and the fish of the sea, all that swim the paths of the seas. O LORD, our Lord, how majestic is your name in all the earth!””
Therefore in Genesis 2, God graciously provided more details about this wonderful creation of the first man, Adam, and his wife, Eve.
Genesis 1 is not about another wife/family who have no purpose in scripture. In our opinion, if it served God's purpose to give Adam a wife before Eve and there was some lesson that we could learn from it, then God would have given us more details and she would have been mentioned in additional scriptures.
