'Laban said to him, Surely you are my bone and my flesh' means joined together as regards truths and as regards goods. 'And he dwelt with him for a full month' means a new state of life. 'And Laban said to Jacob, Because you are my brother' means, because they are kindred, by virtue of good. 'Should you serve me for nothing? Tell me, what shall your reward be?' means that there must be a means by which they are joined together.
