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.

3161. 'Behold, Rebekah is before you; take her and go, and let her be your master's son's wife, as Jehovah has spoken' means consent inspired from the Lord. This too could be shown by an explanation of all the individual words, the general import of these in the internal sense being the meaning that has just been stated. The implications are as follows: When the Lord lived in the world He made the Human within Himself Divine by His own power, the human with everyone having its beginnings in the inmost part of the rational, 2106, 2194. This verse describes how He made it Divine, that is to say, already so as of good and of truth. The good there came from His essential Divinity, that is, from Jehovah the Father from whom He had been conceived; but the truth there had to be acquired by the ordinary way, as with every other human being.

[2] It is well known that nobody is born rational but merely into the ability to become so, and that he becomes rational by means of factual knowledge, that is to say, by means of cognitions which divide up into many genera and species, the first of which are the means leading on to those next to them, and so on in order to the last of all which are cognitions of the spiritual things of the Lord's kingdom and are called matters of doctrine. These latter cognitions are learned in part from the doctrine of faith, in part directly from the Word, and in part therefore by a person's own efforts, as is also well known. As long as these matters of doctrine remain solely in the memory they are merely factual truths and have not as yet been made over to the individual as his own. They first become made over to him when he starts to love them for the sake of life, and more so when he applies them to life. When this happens truths are raised up from the natural memory into the rational part of the mind and are there joined to good. And when they have been joined they are no longer matters of knowledge but of life, for in that case a person is no longer learning from truths how to live but actually living by them. In this way truths come to be his own and become matters of the will. He accordingly enters the heavenly marriage, for the heavenly marriage consists in good and truth joined together in the rational. With men these things are accomplished by the Lord.

[3] But in Himself the Lord did this by Himself, unaided. From the Divine itself He not only begot the Rational as regards Good, but also through this the Natural as regards Truth, which He joined to Good. For it is good that chooses truth for itself and also gives form to it, for good acknowledges nothing else as truth but that which is compatible with it. Thus Divine good that was the Lord's moulded Truth for itself. Nor did it acknowledge as Truth anything else than that which would be compatible with Divine Good, that is, which would be Divine of Itself. Thus He achieved every single thing by His own power. These are the things that are meant by 'acknowledgement that it was the Lord's alone' and by 'consent inspired from the Lord'.
