Genesis 29:25-27

25When morning came, there was Leah! So Jacob said to Laban, “What is this you have done to me? I served you for Rachel, didn’t I? Why have you deceived me?” 26Laban replied, “It is not our custom here to give the younger daughter in marriage before the older one.

27Finish this daughter’s bridal week; then we will give you the younger one also, in return for another seven years of work.”
