And Laban said unto him (giving utterance to the impression Jacob's recital had produced upon his mind), Surely thou art my bone and my flesh—i.e. my blood relation (cf. 9:2; 2 Samuel 5:1).

Genesis 41:1; Numbers 11:20), or a month as regards time, "the second substantive describing the general notion of which the first is a specification" (Kalisch).
