9959. 'And make for them linen undergarments' means an external level of conjugial love. This is clear from the meaning of 'undergarments' as an external level of conjugial love, dealt with below; and from the meaning of 'linen' as external truth or natural truth, also dealt with below. The reason why an external level of conjugial love is meant by 'undergarments' is that garments or coverings derive their meaning from the part of the body they cover, 9827, and the loins and genital organs, which the undergarments clothe or cover, mean conjugial love. For 'the loins' and their meaning this love, see 3021, 4280, 4575; and for 'the genital organs' and their meaning it, 4462, 5050-5062. What truly conjugial love is will be stated below in 9960.

[2] The undergarments were made from linen because 'linen' or 'flax' means external truth or natural truth, 7601, and what constitutes the actual external is truth. The reason why truth constitutes the external is that internal things terminate in external ones and rest on them as their underlying supports, and the underlying supports of good are truths. These are like the foundations on which a house is built or on which a house rests, which is why the truths of faith springing from good are meant by the foundations of a house, 9643. Truths furthermore are what protect forms of good from and withstand evils and falsities, all the power that good possesses being exerted by means of truths, 9643. So it is also that the last and lowest part of heaven is inhabited by those who are guided by truths of faith springing from good. So it is also therefore that what is last or most external with a person, namely his external skin, corresponds to those in heaven who are guided by the truths of faith, 5552-5559, 8980, yet not to those who uphold faith separated from good, since they are not in heaven. From all this it may now be recognized why the undergarments were made from linen or flax. Aaron's undergarment however, when he was clothed with the garments which were 'for glorious adornment', and which have been the subject in the present chapter, was made of fine linen together with interwoven fine linen, as is evident from a later chapter where it says,

They made tunics of fine linen, the work of a weaver, and a turban of fine linen, and attractive headdresses ¹ from fine linen, and linen undergarments with fine twined linen. Exodus 39:27-28.

But when he was clothed with the 'holy garments' Aaron's undergarment was made of linen alone, as is clear from the following in Moses,

When Aaron comes into the sanctuary within the veil he shall put on the holy linen tunic, and the linen undergarment shall be over his flesh, and he shall gird himself with the linen belt, and place the linen turban on himself. These are holy garments. He shall also wash his flesh with water when he puts them on. He shall then first offer burnt offerings and sacrifices, by means of which he will expiate the holy place from uncleannesses. Leviticus 16:1-end.

[3] The reason why Aaron was to go at that time clothed in the linen garments, which were also called 'the holy garments', was that at that time he was performing the duty of expiating the tent, and also the people and himself from uncleannesses. And every expiation, which was accomplished by means of washings, burnt offerings, and sacrifices, represented purification of the heart from evils and falsities, and so represented regeneration; and purification from evils and falsities, or regeneration, is accomplished by means of the truths of faith. This was why Aaron wore the linen garments then, for the truths of faith are meant by 'linen garments', as stated above.

All purification from evils and falsities is accomplished by means of the truths of faith, see 2799, 5954 (end), 7044, 7918, 9089. So therefore is regeneration, 1555, 2046, 2063, 2979, 3332, 3665, 3690, 3786, 3876, 3877, 4096, 4097, 5893, 6247, 8635, 8638-8640, 8772, 9088, 9089, 9103.

[4] It was for the same reason also that the priest was to put on the linen robe and the linen undergarment when he carried the ash away from the altar, Leviticus 6:9-11, and also that 'the priests, the Levites, from the sons of Zadok' were to put it on, when they entered the sanctuary, regarding whom the following is stated in Ezekiel,

The priests, the Levites, the sons of Zadok, shall enter My sanctuary, and they shall draw near My table to minister to Me. When they enter the gates of the inner court they shall put on the linen garments, and no wool shall come upon them. When they minister in the gates of the inner court, and within, the linen turbans shall be on their heads, and the linen undergarments shall be over their loins. They shall not gird themselves with sweat. ² Ezekiel 44:15-18.

The subject in this passage is the new temple, by which a new Church is meant. By 'the priests, the Levites' those guided by truths springing from good are meant, and by 'the linen garments' the truths of faith by means of which purification and regeneration are accomplished. 'Not girding themselves with sweat' means that the holy things of worship should not be mingled with the human self; for 'sweat' means the human self or proprium, and the human proprium is nothing but evil and falsity, 210, 215, 694, 874-876, 987, 1047, 3812 (end), 8480, 8941.

[5] The reason why the undergarment Aaron wore when he was clothed with the garments 'for glorious adornment' was made of linen together with fine twined linen, as is evident from Exodus 39:27-28, quoted above, was that Aaron in those garments represented the Lord in respect of Divine Good in the heavens, Aaron himself representing the Lord in respect of the Divine Celestial there, his garments the Lord in respect of the Divine Spiritual there emanating from the Divine Celestial, 9814, and fine linen the Divine Spiritual emanating from the Divine Celestial, 5319, 9469.

Footnotes:

9826. 'And a checkered tunic' means Divine Truth inmostly present there, emanating directly from the Divine Celestial. This is clear from the meaning of 'a tunic' as natural truth. But when the subject is Aaron, whose garments represented the forms of truth belonging to the Lord's spiritual kingdom, 9814, 9822, 'a tunic' means Divine Truth inmostly present in that kingdom, thus that which emanates from what is right next to it, namely the Divine Celestial, which is the Lord's Divine Good in the inmost heaven. The fact that such things are meant by 'tunics', see 4677. For the heavens are three - the inmost, which is called celestial; the middle, which is called spiritual; and the lowest, which approaches what is natural. In the inmost heaven the good of love to the Lord is predominant, in the middle one the good of charity towards the neighbour, and in the lowest the good of faith. Those heavens are completely distinct and separate from one another, so much so that nobody in one can possibly pass over into the next. Yet in order that they may still make one heaven they are joined together by means of intermediate angelic communities; in this way one heaven leads on from another. Since therefore Aaron's garments represent the spiritual heaven, and so the forms of truth there in their proper order, it is evident that the inmost garment, called 'a checkered tunic', represents the truth inmostly present there, emanating directly from the Divine Celestial. The word 'checkered' is used because it was a woven garment, as is clear from what follows later on in the Book of Exodus,

They made tunics of fine linen, the work of a weaver, for Aaron and for his sons. Exodus 39:27.

It was made from fine linen in order that truth from a celestial origin might be represented, such truth being meant by 'fine linen', see 9469.
