Genesis 30:4-13

So she gave him her maid Bilhah as a wife, and Jacob went in to her. Bilhah conceived and bore Jacob a son. Then Rachel said, “God has vindicated me, and has indeed heard my voice and has given me a son.” Therefore she named him Dan. Rachel’s maid Bilhah conceived again and bore Jacob a second son. So Rachel said, “With mighty wrestlings I have wrestled with my sister, and I have indeed prevailed.” And she named him Naphtali. When Leah saw that she had stopped bearing, she took her maid Zilpah and gave her to Jacob as a wife. Leah’s maid Zilpah bore Jacob a son. Then Leah said, “How fortunate!” So she named him Gad. Leah’s maid Zilpah bore Jacob a second son. Then Leah said, “Happy am I! For women will call me happy.” So she named him Asher.
