I need to say this. God does not want man to have two wives but He records history. You see the problem when a man have more than one wife. If you don't want problems, listen to the Bible.
When Rachel saw that she was not bearing Jacob any children, she became jealous of her sister. So she said to Jacob, “Give me children, or I’ll die!”2 Jacob became angry with her and said, “Am I in the place of God, who has kept you from having children?”
3 Then she said, “Here is Bilhah, my servant. Sleep with her so that she can bear children for me and I too can build a family through her.”
4 So she gave him her servant Bilhah as a wife. Jacob slept with her, 5 and she became pregnant and bore him a son. 6 Then Rachel said, “God has vindicated me; he has listened to my plea and given me a son.” Because of this she named him Dan.[a]
7 Rachel’s servant Bilhah conceived again and bore Jacob a second son. 8 Then Rachel said, “I have had a great struggle with my sister, and I have won.” So she named him Naphtali.[b]
9 When Leah saw that she had stopped having children, she took her servant Zilpah and gave her to Jacob as a wife. 10 Leah’s servant Zilpah bore Jacob a son. 11 Then Leah said, “What good fortune!”[c] So she named him Gad.[d]
12 Leah’s servant Zilpah bore Jacob a second son. 13 Then Leah said, “How happy I am! The women will call me happy.” So she named him Asher.
