Malachi 2:10 - The Popular Commentary by Paul E. Kretzmann

Have we not all one Father? Hath not one God created us? These questions, with the statement they contain, the prophet places at the head of his discussion, to remind the Jews that they were still, in a peculiar sense, the Lord's people and should keep themselves unspotted from the Gentiles. Why do we deal treacherously, faithlessly, every man against his brother, by profaning the covenant of our fathers? The action on the part of the people which the prophet found it necessary to censure was a violation of the relation sustained to Jehovah as a common Father and as the Author of the covenant which governed all their lives.
