Arcana Coelestia # 9636
9636. 'Ten cubits shall be the length of a board' means that this good is the all in all. This is clear from the meaning of 'ten' as all, dealt with in 4638, 9595; and from the meaning of 'the length' as good, dealt with in 1613, 8898, 9487, 9600, at this point good that lends support, which is the good of merit, this good being meant by the boards of the dwelling-place that were made from shittim wood, 9634, 9635. The reason why this good is the all in all of heaven is that it is the Divine Good itself, which makes the heavens and supports them, 9486. The good that resides with angels is real good, for all good comes from the Lord. Good from any other source is not good.

1382. People inevitably confuse Divine Infinity with infinity of space. And because they do not conceive of infinity of space as anything other than nothingness, as indeed it is, neither do they believe in Divine Infinity. The same applies to Eternity. They cannot conceive of it except as an eternity of time, but it is manifested continually by means of time to those who dwell within [space and] time. The true idea of Divine Infinity is instilled into angels by their being instantaneously under the Lord's view with no intervening space or time even if they came from the ends of the universe. And the true idea of Divine Eternity is instilled into them by the fact that thousands of years do not appear to them as a period of time, almost as if they had lived for only a minute. Both ideas are also instilled by means of the fact that the present with them includes past and future together. Consequently they have no anxiety about things of the future, nor do they ever have any idea of death, but only of life. And so their whole present includes within it the Lord's Eternity and Infinity.
