And Jacob loved Rachel,.... As he seems to have done from the moment he saw her at the well, being beautiful, modest, humble, affable, diligent, and industrious:

and he said, I will serve thee seven years for Rachel thy younger daughter: signifying, that he desired no other wages for his service than that, that he might have her for his wife, at the end of seven years' servitude, which he was very willing to oblige himself to, on that condition; for having no money to give as a dowry, as was customary in those times, he proposed servitude instead of it; though Schmidt thinks this was contrary to custom, and that Laban treated his daughters like bondmaids, and such as are taken captives or strangers, and sold them, of which they complain, Genesis 31:15.

And Jacob loved Rachel; and said, I will serve thee seven years for Rachel thy younger daughter.

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.

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, Heb 6:10. If we know how to value the happiness of heaven, the sufferings of this present time will be as nothing to us. An age of work will be but as a few days to those that love God, and long for Christ's appearing. Jacob, who had imposed upon his father, is imposed upon by Laban, his father-in-law, by a like deception. Herein, how unrighteous soever Laban was, the Lord was righteous: see Jud 1:7. Even the righteous, if they take a false step, are sometimes thus recompensed in the earth. And many who are not, like Jacob, in their marriage, disappointed in person, soon find themselves, as much to their grief, disappointed in the character. The choice of that relation ought to be made with good advice and thought on both sides. There is reason to believe that Laban's excuse was not true. His way of settling the matter made bad worse. Jacob was drawn into the disquiet of multiplying wives. He could not refuse Rachel, for he had espoused her; still less could he refuse Leah. As yet there was no express command against marrying more than one wife. It was in the patriarchs a sin of ignorance; but it will not justify the like practice now, when God's will is plainly made known by the Divine law, Le 18:18, and more fully since, by our Saviour, that one man and woman only must be joined together, 1Co 7:2.
