487. 'Days means periods of time and states in general. This has been shown in Chapter 1, where the 'days of creation' have no other meaning. In the Word it is very common for a whole period of time to be called 'a day', as it clearly is in the present verse and in verses 5, 8, 11, 14, 17, 20, 23, 27, 31, below; and therefore the states that belong to periods of time in general are meant by 'days' as well. And when 'years' is attached, then periods of years mean the natures of those states, and so the states in particular.

[2] The most ancient people had their own particular numbers which they would use to mean different aspects of the Church - for instance, the numbers three, seven, ten, twelve, and many which they obtained from these and other numbers - and in so doing incorporated states of the Church. These numbers therefore contain arcana that would require considerable effort to unravel. Really a number was an evaluation of the states of the Church. The same feature occurs throughout the Word, especially in the prophetical. And the religious ceremonies of the Jewish Church also entail numbers specifying periods of time as well as quantities; for example, in connection with sacrifices, minchahs, oblations, and other practices, which in every case have special reference to holy things. Consequently eight hundred in this verse, nine hundred and thirty in the next, and the numbers of years mentioned in the verses that follow after that, embody in particular more matters than can possibly be retold; matters, that is to say, which have to do with changes in the state of their Church in relationship to their own general state. Later on, in the Lord's Divine mercy, the meaning of the simple numbers up to twelve will be given, for without knowing these first of all no one can grasp what compound numbers mean.

2798. That 'Abraham took the pieces of wood for the burnt offering' means the merit of righteousness is clear from what has been stated and shown above in 2784, and so without further explanation.

[2798a] 'And laid them on Isaac [his son]' means that it, that is to say, the merit of righteousness, was joined to the Divine Rational. This becomes clear from the representation of 'Isaac' as the Lord's Divine Rational, often dealt with already, and from the meaning of 'laying it on him' as allying it. The expression 'his son' is used because the Lord's Divine Human was not only conceived but was also born from Jehovah. The Lord's conception from Jehovah is very well known from the Word of the Lord, and therefore He is called 'Son of the Most High', 'Son of God', and 'Only Begotten of the Father' in Matthew 2:15; 3, 16, 17; 16:13-17; 17:5; 27:43, 54; Mark 1:11; 9:7, 9; 14:61-62; Luke 1:31-32, 35; 3:21-22; 9:35; 10:22; John 1:14, 18, 49; 3:13, 16-18; 5:20-27; 6:69; 9:34-35, 38; 10:35-36; 20:30-31, and besides these in very many other places where He calls Jehovah His Father.

[2] It is also well known that He was born of a virgin Mary, yet even so like any other. But when He was born again, that is, became Divine, this was from Jehovah who dwelt within Him and who was Himself as to the very Being (Esse) of life. The union of the Divine Essence and the Human Essence was effected mutually and reciprocally, so that He united the Divine Essence to the Human Essence, and the Human Essence to the Divine Essence, see 1921, 1999, 2004, 2005, 2018, 2025, 2083, 2508, 2523, 2618, 2628, 2632, 2728, 2729. From this it may become clear that the Lord made the Human within Himself Divine from His own power and in so doing became Righteousness. That which was allied to the Divine Rational when He underwent inmost temptation was the merit of righteousness; and it was from the Divine Rational that He fought, and it was against it that evil genii fought, until He glorified that Divine Rational also. These are the things meant in the internal sense by Abraham's laying the pieces of wood for the burnt offering on Isaac his son, and they are the things which angels perceive when these words are being read.
