Genesis 31:42

Except the God of my father, the God of Abraham, and the fear of Isaac, had been with me, surely thou hadst sent me away now empty. God hath seen mine affliction and the labour of my hands, and rebuked thee yesternight.

Jacob's words are his answer to Laban's complaint that he had left secretly without a farewell feast or parting celebration, and in that answer he plainly lays open Laban's selfish and grasping policy while calling on Laban himself as witness to his own faithfulness and honesty. They were spoken after twenty years of service in Laban's house and household, a time marked by injustice, affliction and hard service. Those twenty years were fourteen years for his two daughters and six years for his cattle, during which his wages were changed ten times.

He declares in them that the God of his father, the God of Abraham, and the Fear of Isaac had been with him and had stayed with him through all that time. The title Fear of Isaac identifies the God whom Isaac revered. Without that divine presence Laban would have sent him away empty, with nothing. God had seen his affliction and the labor and work of his hands.

God rebuked Laban and spoke to him the night before, intervening against him. That rebuke restrained Laban from carrying out his hostile purpose and protected Jacob as he left for Canaan. By speaking to Laban, God stopped him and forbade him to force Jacob to return or to press him by threats or by flattering inducements. Laban's treatment of Jacob had included withholding his daughters' marriage dowry and acting toward Jacob with craft and harshness.
