26 Laban said, "This is not done in our country-giving 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 as a wife. 29 (Laban gave his maid Bilhah to his daughter Rachel to be her maid.) 30 So Jacob went in to Rachel also, and he loved Rachel more than Leah. He 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.
