23. Nothing is more common in the Word than for the word 'day' to be used to mean the particular time at which events take place, as in Isaiah,

The day of Jehovah is near. Behold, the day of Jehovah comes. I will make heaven tremble, and the earth will be shaken out of its place, on the day of My fierce anger. Its time is close at hand, and its days will not be prolonged. Isaiah 13:6, 9, 13, 22.

And in the same prophet,

Her antiquity is in the days of antiquity. On that day Tyre will be forgotten for seventy years, like the days of one king. Isaiah 23:7, 15.

Since 'day' stands for the particular time it also stands for the state associated with that particular time, as in Jeremiah, Woe to us, for the day has declined, for the shadows of evening have lengthened! Jeremiah 6:4

And in the same prophet,

If you break My covenant that is for the day and My covenant that is for the night, so that there is neither daytime nor night at their appointed time. Jeremiah 33:20, 25.

Also,

Renew our days as of old. Lamentations 5:21.

2795. 'And return to you' means conjunction after that. This too becomes clear without explanation. The subject of this chapter being the Lord's severest and inmost temptations, all the states are described which He assumed when undergoing those temptations. The first state is described in verse 3, the second state in the present verse, the third state in the verse that follows next and in all the rest after that. But these states cannot possibly be explained to the ordinary mind unless many other things are known first, not only about the Lord's Divine which is represented here by 'Abraham' but also about His Divine Human which is represented by 'Isaac', and about the state - when He went into and underwent the conflicts brought about by temptations - of this Rational, meant here by 'the boy'. In addition to this one has to know what the first rational was, and the nature of it, as well as the natural that went with that rational, and also the nature of the state when one was joined to the other, and the nature of the state when they were more or less separated. What is more, one needs to know many things regarding temptations, such as what exterior and interior temptations are, and from this what were the inmost and severest temptations that were the Lord's, which are the subject in this chapter. As long as all these matters remain unknown the things within this verse cannot possibly be described intelligibly. And if they were described, even in the clearest possible manner, they would still appear obscure. To angels, since they dwell in the light of heaven flowing from the Lord, all these matters are plain and clear, and indeed blessed because these matters are supremely heavenly.

[2] This alone need be said here, that the Lord could not possibly be tempted when He was one with the Divine itself, for the Divine is infinitely above all temptation. But He could experience temptation as to His human. This is the reason why, when He was to undergo the severest and inmost temptations, He joined the first human to Himself, that is to say, the rational and the natural degrees of it, as described in verse 3, and after that separated Himself from them, as stated in the present verse, though still retaining certain traits through which He could be tempted. It is for this reason that here Isaac is not spoken of as 'my son' but as 'the boy', an expression used to mean the Divine Rational in that particular state, that is to say, in a state of truth, equipped for the severest and inmost conflicts brought about by temptations, see 2793. The truth that neither the Divine itself nor the Divine Human could be tempted may become clear to anyone merely from the fact that not even angels can approach the Divine, still less the spirits who bring temptations about, and least of all the hells. From all this it is evident why the Lord came into the world and took on the human state of being with all its weakness, for by doing so He was able to be tempted as regards the human and by means of temptations to suppress the hells. He was able to restore every single thing to obedience and to order, and to save the human race which had removed itself so far away from the Supreme Divine.
