John Calvin on Genesis 31:54

54. And called his brethren to eat bread. In courteously receiving his kindred, by whom he had been ill-treated, as his guests, Jacob showed his kindness. Moses also intimates that it was by the special favor of God that, after the most dreadful storm which threatened the holy man with destruction, a placid serenity suddenly shone forth. To the same cause is to be assigned what immediately follows, that Laban departed in a friendly manner: for by this method the Lord openly manifested himself as the guardian of his servant, seeing that he wonderfully delivered him as a lost sheep out of the jaws of the wolf. And truly, not only was the fury of Laban appeased; but he put on paternal affection, as if he had been changed into a new man.
