Genesis 30:9-13

When Leah saw that she wasn’t having any more children, she gave her maid Zilpah to Jacob for a wife. Zilpah had a son for Jacob. Leah said, “How fortunate!” and she named him Gad (Lucky). When Leah’s maid Zilpah had a second son for Jacob, Leah said, “A happy day! The women will congratulate me in my happiness.” So she named him Asher (Happy).
