23 But in the evening he took his daughter Leah and brought her to Jacob, and he went in to her. 24 (Laban gave[1] his female servant Zilpah to his daughter Leah to be her servant.) 25 And in the morning, behold, it was Leah! And Jacob said to Laban, "What is this you have done to me? Did I not serve with you for Rachel? Why then have you deceived me?" 26 Laban said, "It is not so done in our country, to give the younger before the firstborn. 27 Complete the week of this one, and we will give you the other also in return for serving me another seven years." 28 Jacob did so, and completed her week. Then Laban gave him his daughter Rachel to be his wife. 29 (Laban gave his female servant Bilhah to his daughter Rachel to be her servant.) 30 So Jacob went in to Rachel also, and he loved Rachel more than Leah, and served Laban for 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.
