 place of his son, under divine direction, not only was animal sacrifice substituted for human, and sanctioned as an acceptable symbol of spiritual self-sacrifice, but the offering of human sacrifices by the heathen was condemned and rejected as an ungodly ἐθελοθρησεία. And this was done by Jehovah, the God of salvation, who prevented the outward completion of the sacrifice. By this the event acquires prophetic importance for the Church of the Lord, to which the place of sacrifice points with peculiar clearness, viz., Mount Moriah, upon which under the legal economy all the typical sacrifices were offered to Jehovah; upon which also, in the fulness of time, God the Father gave up His only-begotten Son as an atoning sacrifice for the sins of the whole world, that by this one true sacrifice the shadows of the typical sacrifices might be rendered both real and true. If therefore the appointment of Moriah as the scene of the sacrifice of Isaac, and the offering of a ram in his stead, were primarily only typical in relation to the significance and intent of the Old Testament institution of sacrifice; this type already pointed to the antitype to appear in the future, when the eternal love of the heavenly Father would perform what it had demanded of Abraham; that is to say, when God would not spare His only Son, but give Him up to the real death, which Isaac suffered only in spirit, that we also might die with Christ spiritually, and rise with Him to everlasting life (Rom 8:32; Rom 6:5, etc.).

verses 20-24
Descendants of Nahor. - With the sacrifice of Isaac the test of Abraham's faith was now complete, and the purpose of his divine calling answered: the history of his life, therefore, now hastens to its termination. But first of all there is introduced quite appropriately an account of the family of his brother Nahor, which is so far in place immediately after the story of the sacrifice of Isaac, that it prepares the way for the history of the marriage of the heir of the promise. The connection is pointed out in Gen 22:20, as compared with Gen 11:29, in the expression, “ she also.” Nahor, like Ishmael and Jacob, had twelve sons, eight by his wife Milcah and four by his concubine; whereas Jacob had his by two wives and two maids, and Ishmael apparently all by one wife. This difference with regard to the mothers proves that the agreement as to the number twelve rests upon a good historical tradition, and is no product of a later
