Genesis 22:15

After Abraham had offered the ram, the angel of the Lord called to him a second time from heaven, and with a solemn oath renewed the former promises, as a reward for this proof of his obedience of faith (cf. Gen 12:2-3). To confirm their unchangeableness, Jehovah swore by Himself (cf. Heb 6:13.), a thing which never occurs again in His intercourse with the patriarchs; so that subsequently not only do we find repeated references to this oath (Gen 24:7; Gen 26:3; Gen 50:24; Exo 13:5, Exo 13:11; Exo 33:1, etc.), but, as Luther observes, all that is said in Psa 89:36; Psa 132:11; Psa 110:4 respecting the oath given to David, is founded upon this. Sicut enim promissio seminis Abrahae derivata est in semen Davidis, ita Scriptura S. jusjurandum Abrahae datum in personam Davidis transfert. For in the promise upon which these psalms are based nothing is said about an oath (cf. 2 Sam 7; Ch1 17:1). The declaration on oath is still further confirmed by the addition of יהוה נאם "edict (Ausspruch) of Jehovah," which, frequently as it occurs in the prophets, is met with in the Pentateuch only in Num 14:28, and (without Jehovah) in the oracles of Balaam, Num 24:3, Num 24:15-16. As the promise was intensified in form, so was it also in substance. To express the innumerable multiplication of the seed in the strongest possible way, a comparison with the sand of the sea-shore is added to the previous simile of the stars. And this seed is also promised the possession of the gate of its enemies, i.e., the conquest of the enemy and the capture of his cities (cf. Gen 24:60). This glorious result of the test so victoriously stood by Abraham, not only sustains the historical character of the event itself, but shows in the clearest manner that the trial was necessary to the patriarch's life of fa…

Abraham's obedience was graciously accepted; but this was not all: here we have it recompensed, abundantly recompensed, before he stirred from the place; probably while the ram he had sacrificed was yet burning God sent him this gracious message, renewed and ratified his covenant with him. All covenants were made by sacrifice, so was this by the typical sacrifices of Isaac and the ram. Very high expressions of God's favour to Abraham are employed in this confirmation of the covenant with him, expressions exceeding any he had yet been blessed with. Note, Extraordinary services shall be crowned with extraordinary honours and comforts; and favours in the promise, though not yet performed, ought to be accounted real and valuable recompences. Observe, 1. God is pleased to make mention of Abraham's obedience as the consideration of the covenant; and he speaks of it with an encomium: Because thou hast done this thing, and hast not withheld thy son, thine only son, Gen 22:16. He lays a strong emphasis on this, and (Gen 22:18) praises it as an act of obedience: in it thou hast obeyed my voice, and to obey is better than sacrifice. Not that this was a proportionable consideration, but God graciously put this honour upon that by which Abraham had honoured him. 2. God now confirmed the promise with an oath. It was said and sealed before; but now it is sworn: By myself have I sworn; for he could swear by no greater, Heb 6:13. Thus he interposed himself by an oath, as the apostle expresses it, Heb 6:17. He did (to speak with reverence) even pawn his own life and being upon it (As I live), that by all those immutable things, in which it was impossible for God to lie, he and his might have strong consolation. Note, If we exercise faith, God will encourage it. Improve the promises, and…

22:15-19 After the event, God again confirmed his covenant with Abraham (cp. 15:5, 18-21; 17:3-8). His descendants would be numerous like the stars in the sky (cp. 26:4), like the sand on the seashore (cp. 32:12), and like the dust of the earth (cp. 13:16; 28:14).
