Genesis 30:36

And he set three days' journey betwixt himself and Jacob; and Jacob fed the rest of Laban's flocks. By putting his own sons in charge of his flocks and by placing such a great distance between the two sets of flocks, Laban thought he had effectually curbed Jacob's ambition. His entire conduct was that of a selfish, covetous man, who made use of every possible means to reduce Jacob's wages.
