Genesis 31:29

The God of your fathers spake to me yesterday We find here that Laban, whatever his disposition was, and how great soever his anger, paid regard to the heavenly vision. For though he supposed that he had both right and strength on his side, either to revenge the wrong or recover the right, yet he owns himself under the restraint of God's power; he durst not injure one whom he saw to be the particular care of Heaven. It seems probable that God, who can change the heart in a moment, effected a sudden alteration in his disposition toward Jacob.
