(16) And the city lieth foursquare . . .—The city is foursquare, because the length and breadth are equal; but it is added that the height also is equal to the length and breadth, the city thus presents the symbol of perfect symmetry; this is all that is needed. Many interpreters are nervously anxious about the monstrous appearance of a city whose walls measured three thousand stadii (the word rendered “furlongs” is properly stadii); but there is no need to be nervous about the symbols; the city is not designed, any more than the vision of Revelation 4, or the vision of Ezekiel (Ezekiel 1) to be represented by painting to the eye: the attempt to do so only ends in the production of grotesque and profane pictures. It is not needful, however, in this case to suppose the actual wall to have been 3,000 stadii in height; the city is placed on a hill, the foundations are upon the holy hill, and the deep strong mountain foundations may be included in the measurement. The main thought, however, is to realise the harmony and proportion of that community, in which broad and low and high will meet, and in which no truth will be exaggerated or distorted; in which no disproportioned adjustments will mar its social order; in which all those who are inbuilt as living stones will be measured, not by the false estimates of worldly thoughts (comp. James 2:4), but by the golden reed of the sanctuary.

21:9-21 God has various employments for his holy angels. Sometimes they sound the trumpet of Divine Providence, and warn a careless world; sometimes they discover things of a heavenly nature of the heirs of salvation. Those who would have clear views of heaven, must get as near to heaven as they can, on the mount of meditation and faith. The subject of the vision is the church of God in a perfect, triumphant state, shining in its lustre; glorious in relation to Christ; which shows that the happiness of heaven consists in intercourse with God, and in conformity to him. The change of emblems from a bride to a city, shows that we are only to take general ideas from this description. The wall is for security. Heaven is a safe state; those who are there, are separated and secured from all evils and enemies. This city is vast; here is room for all the people of God. The foundation of the wall; the promise and power of God, and the purchase of Christ, are the strong foundations of the safety and happiness of the church. These foundations are set forth by twelve sorts of precious stones, denoting the variety and excellence of the doctrines of the gospel, or of the graces of the Holy Spirit, or the personal excellences of the Lord Jesus Christ. Heaven has gates; there is a free admission to all that are sanctified; they shall not find themselves shut out. These gates were all of pearls. Christ is the Pearl of great price, and he is our Way to God. The street of the city was pure gold, like transparent glass. The saints in heaven tread gold under foot. The saints are there at rest, yet it is not a state of sleep and idleness; they have communion, not only with God, but with one another. All these glories but faintly represent heaven.And the city lieth four-square - It was an exact square. That is, there was nothing irregular about it; there were no crooked walls; there was no jutting out, and no indentation in the walls, as if the city had been built at different times without a plan, and had been accommodated to circumstances. Most cities have been determined in their outline by the character of the ground - by hills, streams, or ravines; or have grown up by accretions, where one part has been joined to another, so that there is no regularity, and so that the original plan, if there was any, has been lost sight of. The New Jerusalem, on the contrary, had been built according to a plan of the utmost regularity, which had not been modified by the circumstances, or varied as the city grew. The idea here may be, that the church, as it will appear in its state of glory, will be in accordance with an eternal plan, and that the great original design will have been fully carried out.

And the length is as large as the breadth - The height also of the city was the same - so that it was an exact square.

And he measured the city with the reed, twelve thousand furlongs - As eight furlongs make a mile, the extent of the walls, therefore, must have been three hundred and seventy-five miles. Of course, this must preclude all idea of there being such a city literally in Palestine. This is clearly a figurative or symbolical representation; and the idea is, that the city was on the most magnificent scale, and with the largest proportions, and the description here is adopted merely to indicate this vastness, without any idea that it would be understood "literally."

The length, and the breadth, and the height of it are equal - According to this representation, the height of the city, not of the walls (compare Revelation 21:17), would be three hundred and seventy-five miles. Of course, this cannot be understood literally, and the very idea of a literal fulfillment of this shows the absurdity of that method of interpretation. The idea intended to be conveyed by this immense height would seem to be that it would contain countless numbers of inhabitants. It is true that such a structure has not existed, and that a city of such a height may seem to be out of all proportion; but we are to remember:

(a) that this is a "symbol"; and,

(b) that, considered as one mass or pile of buildings, it may not seem to be out of proportion. It is no uncommon thing that a house should be as high as it is long or broad.

The idea of vastness and of capacity is the main idea designed to be represented. The image before the mind is, that the numbers of the redeemed will be immense.

16. twelve thousand furlongs—literally, "to twelve thousand stadii": one thousand furlongs being the space between the several twelve gates. Bengel makes the length of each side of the city to be twelve thousand stadii. The stupendous height, length, and breadth being exactly alike, imply its faultless symmetry, transcending in glory all our most glowing conceptions. The church militant, measured by the reed of the word, is unequal in its parts; some parts of it are purer than others; but in the new Jerusalem all parts shall be equal in perfection and purity, as all the sides of a thing four square are equal.

And the city lieth four square,.... To the four corners of the world, from whence its inhabitants come, and denotes the regularity, uniformity, perfection, and immovableness of it.

And the length is as large as the breadth; this church state will be all of a piece, perfect, entire, and wanting nothing.

And he measured the city with the reed, twelve thousand furlongs; or fifteen hundred miles; a monstrously large city indeed! such an one as never was upon earth; see Ezekiel 48:35 and which shows, that this is not to be understood literally, but mystically; and intends the capaciousness of it, here being room enough for all the twelve tribes of Israel; that is, for all the elect of God; for as in Christ's Father's house, so in this kingdom state of his, there will be many mansions, or dwelling places, enough for all his people. This city will hold them all. The Jews (h) say of Jerusalem, that in time to come it shall be so enlarged, as to reach to the gates of Damascus, yea, to the throne of glory.

The length, and the breadth, and the height of it are equal. A perfectly uniform state! according to the Ethiopic version, it is in length twelve thousand furlongs, and every measure equal, so that it is so many furlongs in length, breadth, and height.

(h) Shirhashirim Rabba, fol. 24. 1.

{14} And the city lieth {b} foursquare, and the length is as large as the breadth: and he measured the city with the reed, twelve thousand furlongs. The length and the breadth and the height of it are equal.

(14) The measure and form most equal, in two verses.

(b) A foursquare figure has equal sides, and outright corners, and therefore the Greeks call by this name those things that are steady, and of continuance and perfect.
