26 "It's not our custom here to marry off a younger daughter ahead of the firstborn," Laban replied. 27 "But wait until the bridal week is over; then we'll give you Rachel, too-provided you promise to work another seven years for me." 28 So Jacob agreed to work seven more years. A week after Jacob had married Leah, Laban gave him Rachel, too. 29 (Laban gave Rachel a servant, Bilhah, to be her maid.) 30 So Jacob slept with Rachel, too, and he loved her much more than Leah. He then stayed and worked for Laban the additional 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.
