genesis 29:18 And Jacob loved Rachel; and said, I will serve thee seven years for Rachel thy younger daughter. - Free Bible Online

      18. I will serve thee seven years for Rachel thy daughter--A proposal of marriage is made to the father without the daughter being consulted, and the match is effected by the suitor either bestowing costly presents on the family, or by giving cattle to the value the father sets upon his daughter, or else by giving personal services for a specified period. The last was the course necessity imposed on Jacob; and there for seven years he submitted to the drudgery of a hired shepherd, with the view of obtaining Rachel. The time went rapidly away; for even severe and difficult duties become light when love is the spring of action.
