3-5 Rachel said, “Here’s my maid Bilhah. Sleep with her. Let her substitute for me so I can have a child through her and build a family.” So she gave him her maid Bilhah for a wife and Jacob slept with her. Bilhah became pregnant and gave Jacob a son.
3 And she said, See here, take my maid Bilhah and have intercourse with her; and [when the baby comes] she shall deliver it upon my knees, that I by her may also have children.
All the people in the town square that day, backing up the elders, said, “Yes, we are witnesses. May God make this woman who is coming into your household like Rachel and Leah, the two women who built the family of Israel. May God make you a pillar in Ephrathah and famous in Bethlehem! With the children God gives you from this young woman, may your family rival the family of Perez, the son Tamar bore to Judah.” * * *
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).
