When Leah saw that she had ceased bearing children, she took her maid Zilpah and gave her to Jacob as a wife.
So, after Abram had lived ten years in the land of Canaan, Sarai, Abram's wife, took Hagar the Egyptian, her slave-girl, and gave her to her husband Abram as a wife.
(Laban gave his maid Zilpah to his daughter Leah to be her maid.)
She conceived again and bore a son, and said, “This time I will praise the Lord”; therefore she named him Judah; then she ceased bearing.
Then Leah's maid Zilpah bore Jacob a son.
And God heeded Leah, and she conceived and bore Jacob a fifth son.
So she gave him her maid Bilhah as a wife; and Jacob went in to her.
Then Rachel said, “With mighty wrestlings I have wrestled with my sister, and have prevailed”; so she named him Naphtali.
(these are the children of Zilpah, whom Laban gave to his daughter Leah; and these she bore to Jacob—sixteen persons).
