23 At evening, though, he got his daughter Leah and brought her to the marriage bed, and Jacob slept with her. 24 (Laban gave his maid Zilpah to his daughter Leah as her maid.) 25 Morning came: There was Leah in the marriage bed! Jacob confronted Laban, "What have you done to me? Didn't I work all this time for the hand of Rachel? Why did you cheat me?" 26 "We don't do it that way in our country," said Laban. "We don't marry off the younger daughter before the older. 27 Enjoy your week of honeymoon, and then we'll give you the other one also. But it will cost you another seven years of work." 28 Jacob agreed. When he'd completed the honeymoon week, Laban gave him his daughter Rachel to be his wife. 29 (Laban gave his maid Bilhah to his daughter Rachel as her maid.) 30 Jacob then slept with her. And he loved Rachel more than Leah. He worked for Laban another seven years.

Commentary on Genesis 29:15-30
(Read Genesis 29:15-30)
During the month that Jacob spent as a guest, he was not idle. Wherever we are, it is good to employ ourselves in some useful business. Laban was desirous that Jacob should continue with him. Inferior relations must not be imposed upon; it is our duty to reward them. Jacob made known to Laban the affection he had for his daughter Rachel. And having no wordly goods with which to endow her, he promises seven years' service Love makes long and hard services short and easy; hence we read of the labour of love, 1 Corinthians 7:2.
