Genesis 31:50

If thou shalt afflict. In spite of his selfish disposition, Laban’s paternal instinct made him jealous for the welfare of his daughters and solicitous of their future. This seems a little strange in the light of Laban’s own conduct (v. 15); he himself had been the cause of Jacob’s polygamy. But that, as it were, was all within the family. And if Jacob should take other wives, the affection and inheritance that would fall to his own daughters and to their children would thereby be diminished. Laban remained possessive to the very end.
