Abraham called the place Jehovah-jireh That is, The Lord will provide, alluding, it seems, to what he had said, Genesis 22:8, God will provide himself a lamb. This was purely the Lord's doing: let it be recorded for the generations to come, that the Lord will see and provide; will always have his eyes upon his people in their straits, that he may come in with seasonable succour in the critical juncture: as it is said to this day The time when Moses wrote this account; or is become a proverb in frequent use; In the mount of the Lord it shall be seen The words thus rendered, namely, the words of the proverb, should certainly be translated either, In the mount the Lord well appear, or rather, In the mount the Lord will provide. That is, in his people's greatest perplexities and extremities, and when matters are come to a crisis, the Lord will appear to provide for them. Or, according to the proverb used with us, “Man's extremity is God's opportunity.”
Genesis 22:15. And the angel Christ, called unto Abraham Probably while the ram was yet burning. Very high expressions are here used of God's favour to Abraham, above any he had yet been blessed with. Multiplying I will multiply thee Those that part with any thing for God, shall have it made up to them with unspeakable advantage. Abraham has but one son, and is willing to part with that one in obedience to God; Well, saith God, thou shalt be recompensed with thousands and millions. In blessing I will bless thee 1st, The promise of the Spirit is here included, which is that blessing of Abraham which was to “come upon the Gentiles through Jesus Christ,” Galatians 3:14. 2d, The increase of the church; that believers, his spiritual seed, should be many as the stars of heaven. 3d, Spiritual victories; Thy seed shall possess the gate of his enemies Believers by their faith overcome the world, and triumph over all the powers of darkness. Probably Zacharias refers to this part of the oath, Luke 1:74, “That we, being delivered out of the hand of our enemies, might serve him without fear.” But the crown of all is the last promise, 4th, The incarnation of Christ; In thy seed (one particular person that shall descend from thee, for he speaks not of many, but of one, as the apostle observes, Gal 3:16) shall all the nations of the earth be blessed Christ is the great blessing of the world. Abraham was ready to give up his son for a sacrifice to the honour of God, and on that occasion God promised to give his Son a sacrifice for the salvation of man.
