Ye are the children of the prophets - This is the argumentum ad hominem: as ye are the children or disciples of the prophets, ye are bound to believe their predictions, and obey their precepts; and not only so, but ye are entitled to their promises. Your duty and your interest go hand in hand; and there is not a blessing contained in the covenant which was made with your fathers but belongs to you. Now, as this covenant respected the blessings of the Gospel, you must believe in Jesus Christ, in order to be put in possession of all those blessings.
Ye are the children of the prophets - Greek: “Ye are the sons of the prophets.” The meaning is, not that they were literally the “descendants” of the prophets, but that they were their “disciples,” “pupils,” “followers.” They professed to follow the prophets as their teachers and guides. Teachers among the Jews were often spoken of under the appellation of fathers, and disciples as sons, Matthew 12:27. See notes on Matthew 1:1. As they were the professed disciples of the prophets, they should listen to them. As they lived among the people to whom the prophets were sent, and to whom the promises were made, they should avail themselves of the offer of mercy, and embrace the Messiah.
And of the covenant - Ye are the sons of the covenant; that is, you are of the posterity of Abraham, with whom the covenant was made. The word “sons” was often thus used to denote those to whom any favor pertained. whether by inheritance or in any other way. Thus, Matthew 8:12, “The children (sons) of the kingdom”; John 17:12, “the son of perdition.” The word “covenant” denotes properly “a compact or agreement between equals, or those who have a right to make such a compact, and to choose or refuse the terms.” When applied to God and man, it denotes a firm promise on the part of God; a pledge to be regarded with all the sacredness of a compact, that he will do certain things on certain conditions. It is called a covenant only to designate its sacredness and the certainty of its fulfillment, not that man had any right to reject any of the terms or stipulations. As man has no such right, as he is bound to receive all that his Maker proposes, so, strictly and literally, there has been no compact or covenant between God and man. The promise to which Peter refers in the passage before us is in Genesis 22:18; Genesis 12:3.
In thy seed - Thy posterity. See Romans 4:13, Romans 4:16. This promise the apostle Paul affirms had express reference to the Messiah, Galatians 3:16. The word “seed” is used sometimes to denote an individual Genesis 4:25; and the apostle Galatians 3:16 affirms that there was special reference to Christ in the promise made to Abraham.
All the kindreds - The word translated “kindreds” πατριαὶ patriaidenotes “those who have a common father or ancestor,” and is applied to families. It is also referred to those larger communities which were descended from the same ancestor, and thus refers to nations, Ephesians 3:15. Here it evidently refers to “all nations.” Be blessed - Be made happy.
Be blessed - Be made happy.
