Genesis

Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.

And all the people that were in the gate, and the elders, said, We are witnesses. The Lord make the woman that is come into thine house like Rachel and like Leah, which two did build the house of Israel: and do thou worthily in Ephratah, and be famous in Beth–lehem:

And Laban gave to Rachel his daughter Bilhah his handmaid to be her maid.

And Laban gave unto his daughter Leah Zilpah his maid for an handmaid.
