17 that I will bless you greatly, and I will multiply your seed greatly like the stars of the heavens, and like the sand which is on the seashore. Your seed will possess the gate of his enemies.

Thy seed shall possess the gate of his enemies. He means that the offspring of Abraham should be victorious over their enemies; for in the gates were their bulwarks, and in them they administered judgment. Now, although God often suffered the enemies of the Jews tyrannically to rule over them; yet he so moderated their revenge, that this promise always prevailed in the end. Moreover, we must remember what has before been stated from Paul, concerning the unity of the seed; for we hence infer, that the victory is promised, not to the sons of Abraham promiscuously, but to Christ, and to his members, so far as they adhere together under one Head. For unless we retain some mark which may distinguish between the legitimate and the degenerate sons of Abraham, this promise will indiscriminately comprehend, as well the Ishmaelites and Idumeans, as the people of Israel: but the unity of a people depends on its head. Therefore the prophets, whenever they wish to confirm this promise of God, assume the principle, that they who have hitherto been divided, shall be united, under David, in one body. What further pertains to this subject may be found in the twelfth chapter Genesis 12:1
Shall possess the gate of his enemies - Instead of gate the Septuagint have πολεις, cities; but as there is a very near resemblance between πολεις, cities, and πυλας, gates, the latter might have been the original reading in the Septuagint, though none of the MSS. now acknowledge it. By the gates may be meant all the strength, whether troops, counsels, or fortified cities of their enemies. So Matthew 16:18 : On this rock I will build my Church, and the gates of hell shall not prevail against it - the counsels, stratagems, and powers of darkness shall not be able to prevail against or overthrow the true Church of Christ; and possibly our Lord had this promise to Abraham and his spiritual posterity in view, when he spoke these words.
That in blessing I will bless thee,.... With temporal and spiritual blessings; with the Spirit and all his graces; with Christ and redemption, justification, and salvation by him; and with eternal life, as the gift of God, through him:
and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore: both his natural seed, descending from him in the line of Isaac, and his spiritual seed, both among Jews and Gentiles, that tread in his steps; see Genesis 13:15,
and thy seed shall possess the gate of his enemies: "gate" for "gates", where courts of judicature were held, and which are the security of cities and put for them, and which also include the whole country round about: so that this phrase is expressive of an entire jurisdiction and dominion over them; and was literally fulfilled in the times of Joshua, David, and Solomon; and spiritually in Christ, Abraham's principal seed, when he destroyed Satan and his principalities and powers; overcame the world; made an end of sin and abolished death; and delivered his people out the hands of all their enemies; and in all Abraham's spiritual seed, who are made more than conquerors over them, through Christ that has loved them.
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. Here is a promise, Of the Spirit, In blessing I will bless thee - The Gift of the Holy Ghost; the promise of the Spirit was that blessing of Abraham which was to come upon the Gentiles through Jesus Christ, Galatians 3:14. Of the increase of the church; that believers, his spiritual seed, should be many as the stars of heaven. Of 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, Of 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, Galatians 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.
