37. As for the statement that 'the lights will be for signs, and for set times, and for days, and for years', this contains more arcana than can be presented at this point, though no arcanum at all is visible in the sense of the letter. For now only this can be said: Change in spiritual and celestial things takes place both on general and on particular scales, and is comparable to changes that take place through the day and through the year. Changes through the day are from morning to midday, from then on to evening, and through the night to the morning. Changes in the year similar, from spring to summer, from then on to autumn, and through winter to spring. These bring changes in temperature and amount of daylight, and so in the fertility of the earth. Compared to such changes are the changes that take place in spiritual and celestial things. Life without changes and variations would lead to sameness, and so no life at all. Good and truth would not be recognized and identified, let alone perceived. In the Prophets such changes are called 'ordinances', as in Jeremiah,

[Thus] said Jehovah who gives the sun for light by day and the ordinances of the moon and of the stars for light by night, These ordinances will not depart from before Me. Jeremiah 31:35-36.

And in the same prophet,

Thus said Jehovah, If I have not established My covenant of day and night, the ordinances of heaven and earth . . . Jeremiah 33:25.

But these things will in the Lord's Divine mercy be dealt with at Genesis 8:12.

4482. 'Behold, the land is broad and spacious before them' means extension, that is to say, of truth which is the truth of doctrine. This is clear from the meaning of 'the land' as the Church, dealt with just above in 4480, and from the meaning of 'broad and spacious' as extension as regards truths, and so as regards those taught by doctrine. When in the Word the measurements of something are given, it is not those measurements that are meant in the internal sense but the essential characteristics of a state that is being described. For measurements involve spatial dimensions and in the next life there are no intervals of space, as there are no periods of time, but states which correspond to these, see 2625, 2837, 3356, 3387, 3404, 4321. That being so, lengths, breadths, and heights, which are spatial measurements, mean the aspects of a state - length meaning holiness, height good, and breadth truth, see 650, 1613, 3433, 3434. This then is why 'the land is broad and spacious' means the extension of truth which is the truth of doctrine within the Church.

[2] Anyone who does not know of the existence of anything spiritual in the Word other than that which stands out in the literal sense is bound to be amazed by the statement that 'the land is broad and specious' means the extension of truth which is the truth of doctrine within the Church. But the truth of this statement may be established from places where 'breadth' is mentioned in the Word, as in Isaiah,

Asshur will go through Judah, it will deluge it and pass through and will reach even to the neck; and the outstretchings of its wings will fill the breadth of the land. Isaiah 8:8.

In David,

O Jehovah, You have not shut me up into the hand of the enemy. You have made my feet stand in a broad place. Psalms 31:8.

In the same author,

Out of my distress I called on Jah; He answered me in a broad place. Psalms 118:5.

In Habakkuk,

I am rousing the Chaldeans, a bitter and hasty nation, marching' into the breadths of the earth. Habakkuk 1:6.

'Breadths' here means nothing other than the truth of the Church.

[3] The reason why breadth has this meaning is that in the spiritual world, that is, in heaven, the Lord is the centre of all, for He is the Sun there. Those in a state of good are more interior, their exact position towards the middle being determined by the character and the amount of the good present in them. This is why 'height' is used in reference to good. Those who are in a similar degree of good are also in a similar degree of truth, and so dwell so to speak at the same distance from the centre, or one might say, dwell on the same contour; and this is why 'breadth' is used in reference to truths. Therefore when a person reads the Word the angels present with him do not understand by 'breadth' anything other than truths. When in the Historical sections, for example, the ark, the altar, the temple, and the spaces outside cities are referred to, states of good and truth are perceived by the dimensions indicating the lengths, breadths, and heights of these. The same is so with the new earth, new Jerusalem, and new Temple - described in Chapters 40-47 of Ezekiel - by which heaven and a new Church are meant, as may be seen from the detailed descriptions in those chapters. So also in John where it is said of the New Jerusalem that it will be foursquare, 'its length being as great as its breadth', Revelation 21:16.

[4] Things which in the spiritual world are interior are described as those that are higher, while those that are exterior are described by those that are lower, 2148, for while in the world, no one can conceive of interior things and exterior ones in any other way, for the reason that he dwells within space and time, and things that belong to space and time have entered in among the ideas comprising his thought and have conditioned the majority of these. From this it is also evident that expressions which give the spatial measurements of things such as the height, length, and breadth of them, are in the spiritual sense expressions used to indicate the magnitude of affections for good and affections for truth.
