Genesis 29:27-29 The Voice (VOICE)
27 If you complete this wedding week with Leah, then I will also give you Rachel. But in return, you must serve me another seven years.
Wedding celebrations last seven days, plenty of time for Leah to become pregnant with Laban’s first grandchild.
28 Jacob agreed and completed his week with Leah. And then Laban gave him his daughter Rachel in marriage. 29 Laban gave his servant Bilhah to his daughter Rachel to be her servant.
