Gen. 22:15-24
Consequent on the wondrous type of the far more wondrous sacrifice of the Lord Jesus, we have Jehovah's angel announcing to Abraham His solemn oath on that which deeply concerned both Jews and Gentiles, and we may add God Himself most nearly, and His title to bless not only in His righteous government but in sovereign grace according to His nature.
“And Jehovah's angel called to Abraham a second time from the heavens, and said, By myself I swear, saith Jehovah, that because thou hast done this and hast not withheld thy son, thine only son, blessing I will bless thee, and multiplying I will multiply thy seed as stars of the heavens, and as sand that is on the sea's shore; and thy seed shall possess his enemies' gate; and in thy seed shall all nations of the earth be blessed, because thou hast harkened to my voice. And Abraham returned to his young men; and they rose up and went together to Beer-sheba; and Abraham dwelt at Beer-sheba.
And it came to pass after these things that it was told Abraham, saying, Behold, Milcah, she also hath borne children to thy brother Nachor: Uz his firstborn, and Buz his brother, and Kemuel father of Aram, and Chesed, and Hazo and Pildash and Jidlaph and Bethuel (and Bethuel begot Rebekah). These eight Milcah bore to Nachor, Abraham's brother. And his concubine named Reumah, she also bore Tebah and Gaham and Tahash and Maacah” (vers. 15-24).
Because of Jehovah's appreciation of Abraham's unreserved surrender to Him of what was most precious to his heart, first comes the assurance of rich blessing and great multiplication of his seed according to flesh. It should be for multitude as stars of the heavens and as sand of the seashore. Nor this only, but with power over their adversaries, as befits the earthly people of His choice. Beyond just question Israel is thus in view (ver. 17).
But there follows in ver. 18 a promise intentionally severed, and couched in such terms as point to the True Seed in Whom should all the nations of the earth be blessed. And here not a hint was uttered of a numerous posterity; as indeed the evident aim was to indicate the One on Whom alone depended blessing of a far higher order, and this for “all the nations of the earth.” Here we are recalled to the original promise made to the patriarch and recorded in the last half of Gen. 12:3: “and in thee shall all families of the earth be blessed.” There, as here, it follows the national blessing of the earthly people. It was therefore left open and goes out in unlimited grace as in the gospel. He only could thus speak Who knew the end from the beginning.
Of this the apostle in the power, of the Holy Spirit avails himself in writing to the Galatians (chap. 3), beguiled as they then were into that judaizing of heavenly truth which has been and is the sore bane of Christendom. Works of law are a ruinous principle for sinful man; the promise is by faith, whereby alone believers are blessed with the faithful Abraham. For as many as are of law-works are under curse; not merely such as violate the law, but all that take the ground of law before God. As surely as they do, they being sinful fall under curse. Therefore Deut. 27 is cited, wherein the Holy Ghost passes by all account of the blessings of the six tribes on mount Gerizim, and only gives in detail the curses of the other six on mount Ebal. These alone were effective. The blessings cannot be for guilty man on that ground. It is by faith, says the prophet, the just shall live; and redemption from curse is needed for those under law, that the blessing of Abraham might come to the nations in Christ Jesus, as the gospel declares. Nor is this all. For the Seed is arrived, and the covenant is confirmed, as it was typically in Isaac, dead and risen parabolically. Hence the apostle proceeds, “But to Abraham were addressed the promises, and to his seed"-to the father in Gen. 12, and to his son in chap. 22. “He saith not, ‘And to seeds,' as of many, but as of one, ‘And to thy seed' [where allusion to stars and sand, as well as greatly multiplying,' are quite dropt], which is Christ.”
The reasoning of the apostle, here as elsewhere, only appears weak to presumptuous men, who are unbelieving and so must fail to understand God's mind in it. Where souls accept the divine authority, not only of the Epistle to the Galatians but of Genesis which the Epistle assumes, all is seen to be bright, profoundly true, and of living interest. It is no question of mere grammar, but of context; which, in the promise that distinctly contemplates Israel, makes much of numbers; whereas in that which introduces the Gentiles for blessing, it says not a word about anything of the kind, but only of one, “thy seed.” It was a covenant confirmed beforehand by God; and the law, which came after four hundred and thirty years, does not annul it, so as to make the promise of no effect. Nor does the law clash with the promise: each has its own object; the one, a ministry of death and condemnation; the other, of blessing by faith. Mixing the two does the mischief; and this is exactly to what man is prone, and what scripture ever explicitly sets aside.
In the light of N. T. facts, how the types of Genesis come out! The woman's Seed is surely man, yet more than man, bruised to bruise utterly and forever the old serpent the devil, fallen angel as he is, Abraham's Seed, foreshewn in Isaac dead and risen in figure, portrays the Deliverer in the wholly new condition of man beyond death, able to bless Gentiles in sovereign grace no less than Jews, and unite them to Himself in heavenly glory. And this is just what the gospel now reveals to faith.
The closing verses of the chapter bring before us a brief sketch of Nachor's line (Abraham's brother), whose son Bethuel was father of Rebekah through Milcah the wife, not through Reumah the concubine. How closely this connects itself with Isaac's future we shall have before us in due time, carrying out the purpose of God.
