Genesis 32:15

Ten bulls - The Syriac and Vulgate have twenty; but ten is a sufficient proportion to the forty kine. By all this we see that Jacob was led to make restitution for the injury he had done to his brother. Restitution for injuries done to man is essentially requisite if in our power. He who can and will not make restitution for the wrongs he has done, can have no claim even on the mercy of God.
