354. Come and see. That this signifies attention and perception, is clear from the signification of coming when anything is made visible, as denoting to attend; for by coming, in the spiritual sense, is meant to draw near with the sight, thus to attend; all attention also is from the presence of the sight in the object; and from the signification of beholding, as denoting perception, for by seeing in the Word is signified to understand (as may be seen above, n. 11, 260); here to perceive, because out of the inmost heaven; for what comes out of the inmost heaven, is perceived; but what comes out of the middle heaven, is understood. The reason is, that the inmost heaven is in the good of love, but the middle heaven is in the truths therefrom, and all perception is from good, and all understanding from truths. (Concerning this fact see above, n. 307; what perception is may be seen in the Doctrine of the New Jerusalem 140.)

197. It follows from this that in the Word places and spaces, and all things that in any way relate to space, signify such things as relate to states, such as distances, near, far off, ways, journeys, sojourning, miles and furlongs, plains, fields, gardens, cities and streets, motions, measures of various kinds, long, broad, high, and deep, and innumerable other things; for most things in man's thought from the world take on something from space and time.

[2] I will mention here only what is signified in the Word by length, breadth, and height. In this world, that is called long or broad which is long or broad in relation to space, and the same is true of height. But in heaven, where there is no thought from space, length means a state of good, breadth a state of truth, and height the distinction between them in accordance with degrees (see 38). Such is the meaning of these three dimensions, because length in heaven is from east to west, and those that dwell there are in good of love; while breadth in heaven is from south to north, and those that dwell there are in truth from good (see 148); while height in heaven applies to both of these in respect to degrees. This is why length, breadth, and height have these significations in the Word, as in Ezekiel (from chap. 40 to 48), where the new temple and the new earth, with the courts, chambers, gates, doors, windows, and surroundings are described by measures giving the length, breadth, and height, by which a new church, and the goods and truths that are in it are signified. Otherwise to what purpose would be all those measures?

[3] In like manner the New Jerusalem is described in the Apocalypse in these words:

The city lieth foursquare, and the length thereof is as great as the breadth; and he measured the city with the reed, twelve thousand furlongs; the length, the breadth, and the height are equal (Apocalypse 21:16).

Because "the New Jerusalem" here signifies a new church these measures signify the things of the church, "length" its good of love, "breadth" truth from that good, "height" good and truth in respect to degrees, "twelve thousand furlongs" all good and truth in the complex. Otherwise, how could there be said to be a height of twelve thousand furlongs, the same as the length and the breadth? That "breadth" in the Word signifies truth is evident from David:-

Jehovah, Thou hast not shut me up into the hand of the enemy, Thou hast made my feet to stand in a broad place (Psalm 31:8).

Out of straitness I called upon Jah; He answereth me in a broad place (Psalm 118:5).

Besides other passages (as in Isaiah 8:8; and in Habakkuk 1:6). So in all other cases.
