v.12 And had a wall great and high, and had twelve gates, and at the gates twelve angels, and names written thereon, which are the names of the twelve tribes of the children of Israel:
And had a wall great and high,…. Not the Spirit of God, who separates, sanctifies, and preserves the saints, as Cocceius thinks, for this account respects not the church militant; nor the eternal decree of God, the impassable gulf between heaven and hell, which everlastingly fixes the state of men; for this regards not the ultimate state of happiness: many interpreters understand it of the doctrine of the Gospel, which, as it secures the church now from heretics, and is like a wall very strong and well built, is durable and impregnable; and may be called “great”, because of the great Author of it, and the great things contained in it; and “high”, since it is not to be reached by carnal minds; so none but such who have embraced it shall enter into the new Jerusalem; for all liars, and forgers of doctrinal lies, and who embrace the antichristian lies, shall be without.
Though rather the almighty power of God, which guards his church and people now, and will be their defence in this state, is meant; and which shows the state not to be that of the ultimate glory, which will need no wall, but this will; since an attempt will be made upon the saints in it, though it will be a foolish and fruitless one: and this wall of divine power is very great indeed, and is insuperable by men; God himself is a wall of fire about his people; though it may be best to interpret this of salvation itself, which is by Jesus Christ, if we compare with this text Isaiah 26:1 for those, and those only, who are interested in it, will dwell in the new Jerusalem; and salvation in this state will be enjoyed in its fulness; and this is very great in its author, objects, and matter, being wrought out by the great God, for great sinners, at a great expense, and including grace and glory, and not to be got over or enjoyed by those who have no interest in it.
And had twelve gates; though, strictly speaking, there is but one gate, and that a strait one, which is the Lord Jesus Christ, his person, blood, righteousness, regenerating and sanctifying grace; for as he is the only door into the sheepfold, the church, in its present state, or he only that has faith in him has a right to enter there, and is the only way to heaven and eternal happiness; so he is the only gate into the new Jerusalem, or such only will be admitted there, who are interested in him: but these gates are said to be twelve, in allusion to the twelve apostles, who pointed out to men the way of salvation by Christ; and to the twelve tribes of Israel, who represent all the elect of God, who enter in thereat; and to the twelve gates of Ezekiel’s city, Ezekiel 48:31.
And at the gates twelve angels; meaning either the ministering spirits, in allusion to the cherubim in Genesis 3:24 who are watchers, and encamp about the saints now, and will, as it were, stand sentinels in this camp of the saints, as it is called, Revelation 20:8 and besides, will be made use of in gathering the saints from the several parts of the world, and introducing them into this state; or else the apostles and ministers of the word, often called angels in this book, who will shine with peculiar lustre now, and will appear at the head of the several companies they have been useful to, and bring them as their joy and crown of rejoicing into this glorious state: this clause is wanting in the Alexandrian copy, and in the Syriac version. The Jews speak of “princes”, being appointed over the gates of heaven, east, west, north, and south, with the keys in their hands, whose names they give us[f] Raziel, fol. 35. 2..
And names written thereon, which are the names of the twelve tribes of the children of Israel; not literal, but mystical Israel, whom God has chosen to salvation, Christ has redeemed by his blood, and the Spirit calls by his grace; denoting that all, and each of these, have a right to enter into the new Jerusalem, and will be admitted there, and none but they. In like manner the Jews[g] Zohar in Numb. fol. 70. 4. make mention of a court of the Lord,
“which has twelve gates, according to the computation of the tribes of Israel; on one gate is written Reuben, on another is written Simeon; and so all the tribes of Israel are written on those gates; in the time they go up to appear before the Lord of the world, whoever goes up to this gate, (on which the tribe of Reuben is written,) if he is of the tribe of Reuben they open to him, (and receive him,) if not they cast him without; and so of all whom they do not receive; they open to none but to him who is of that tribe, or whose name is written on the gate.”
