How many wives did Adam have?

Genesis 1:26 says: > 26 Then God said, “And now we will make human beings; they will be like us and resemble us. They will have power over the fish, the birds, and all animals, domestic and wild, large and small.” 27 So God created human beings, making them to be like himself. He created them male and female, 28 blessed them, and said, “Have many children, so that your descendants will live all over the earth and bring it under their control. I am putting you in charge of the fish, the birds, and all the wild animals. Now I wonder why did God put Adam to sleep to make him another wife in Genesis 2:18 which says: > 18 Then the Lord God said, “It is not good for the man to live alone. I will make a suitable companion to help him.” 19 So he took some soil from the ground and formed all the animals and all the birds. Then he brought them to the man to see what he would name them; and that is how they all got their names. 20 So the man named all the birds and all the animals; but not one of them was a suitable companion to help him. > > 21 Then the Lord God made the man fall into a deep sleep, and while he was sleeping, he took out one of the man's ribs and closed up the flesh. 22 He formed a woman out of the rib and brought her to him. 23 Then the man said, “At last, here is one of my own kind — Bone taken from my bone, and flesh from my flesh. ‘Woman’ is her name because she was taken out of man.”
