9726. 'And you shall make for it a grating, a network' means the level of sensory perception, which is the last and lowest. This is clear from the meaning of 'a grating, a network' as external sensory perception, thus that which forms for a person the last and lowest level of life; and since this lowest level is meant by the grating it was placed all the way round the altar. Such sensory perception was represented by the grating because it first sifts so to speak and sorts out those things which enter the human mind and present themselves to the understanding and will, namely truths and forms of good. If the sensory perception is composed of good it does not let anything through other than forms of good, and truths derived from good, and rejects evils and the falsities arising from evil. For sensory perception is the actual ability to perceive things which belong to the understanding and to sense those which belong to the will as they exist on outermost levels, an ability that is perfectly fashioned for the affections for those things. The nature of all this may be illustrated by very many things in the body. Everywhere in the outermost parts within the body there are forms that resemble nets and there are so to speak gratings which sort out the things that flow towards them from the world. Those that are suitable are let through because they are desirable, and those that are unsuitable are rejected because they are loathsome. Extremely sensitive systems such as these exist in the stomach. These let through into the blood the suitable juices of the chyle, because these juices are useful and therefore desirable, and reject the unsuitable because they are harmful and therefore loathsome. The situation is similar with sensory perception, which is the last and lowest level of a person's life. But this level with a person has become totally wrecked, the reason why being that it stands right next to and is exposed to the world and is therefore the last to be regenerated, indeed scarcely anyone at the present day is able to be regenerated down to that level. As regards what the level of sensory perception is like with these people, see what has been shown already concerning it in 4009, 5077, 5081, 5084, 5094, 5125, 5128, 5580, 5767, 5774, 6183, 6201, 6310-6318, 6564, 6598, 6612, 6614, 6622, 6624, 6844, 6845, 6948, 6949, 7442, 7645, 7693, 9212, 9216.

Therefore if a person is to see and have an understanding of the truths of faith and the forms of the good of love he must be raised by the Lord above that level to more internal levels. But the sensory perception meant by 'the grating, the network' around the altar is the sensory perception belonging to the Lord's Divine Human, since the altar is representative of the Lord and of the worship of Him that springs from the good of love, 9714.

2807. 'Abraham said, God will see for Himself to the animal for a burnt offering, my son' means the reply: The Divine Human will provide those who are to be sanctified. This is clear from the meaning of 'seeing to for oneself', when used in reference to God, as foreseeing and providing - for 'to see' in the internal sense nearest to the literal means to understand, 2150, 2325, whereas in the sense yet more interior it means having faith, 897, 2325, while in the highest sense it means foreseeing and providing; and also from the meaning of 'the animal for a burnt offering' as those members of the human race who are to be sanctified, dealt with just above in 2805. That 'the animal for a burnt offering' is here used to mean those who are spiritual is evident from what follows. The kinds of animals used for burnt offering and sacrifice each had a different meaning. That is to say, a lamb meant one thing, a sheep another, a kid and she-goat another, a ram and he-goat another, an ox yet another, as did a young bull and a calf. And young pigeons and turtle doves had meanings different again. It is quite clear that each kind of animal had its own meaning from the fact that it was laid down explicitly which kind were to be sacrificed on each particular day, at each particular religious festival, when atonement was being made, cleansing effected, inauguration carried out, and all other occasions. Which kinds were to be used on which occasions would never have been laid down so explicitly unless each one had possessed some specific meaning.

[2] Clearly all the religious observances or forms of external worship which existed in the Ancient Church, and subsequently in the Jewish, represented the Lord, so that the burnt offerings and sacrifices in particular represented Him since these were the chief forms of worship among the Hebrew nation. And because they represented the Lord they also at the same time represented among men those things that are the Lord's, that is to say, the celestial things of love, and the spiritual things of faith, and as a consequence of this represented the people themselves who were celestial and spiritual or who ought to have been so. This is why 'the animal' here means those who are spiritual, that is, those who belong to the Lord's spiritual Church. As regards 'God will see for Himself to the animal for a burnt offering, my son' meaning that the Divine Human will provide them, this is clear from the fact that here it is not said that 'Jehovah' will see to it but that 'God' will do so. When both of these names occur, as they do in this chapter, Jehovah is used to mean the same as 'the Father', and God the same as 'the Son', so that here the Divine Human is meant; and a further reason for the usage is that the spiritual man, whose salvation comes from the Divine Human, is the subject, see 2661, 2716.
