Rachel saw that she could not have children for Jacob, and she became jealous of her sister. She said to Jacob, "Give me children, or I'll die!"
Jacob became angry with Rachel and asked, "Can I take the place of God, who has kept you from having children?"
She said, "Here's my servant Bilhah. Sleep with her. She can have children for me, and I can build a family for myself through her."
So she gave him her slave Bilhah as his wife, and Jacob slept with her.
Bilhah became pregnant, and she gave birth to a son for Jacob.
Rachel said, "Now God has judged in my favor. He has heard my prayer and has given me a son." So she named him Dan [He Judges].
Rachel's slave Bilhah became pregnant again and gave birth to a second son for Jacob.
Rachel said, "I have had a great struggle with my sister, and I have won!" So she named him Naphtali [My Struggle].
When Leah saw that she had stopped having children, she took her slave Zilpah and gave her to Jacob as his wife.
Leah's slave Zilpah gave birth to a son for Jacob.
Leah said, "I've been lucky!" So she called him Gad [Luck].
