Goats, as in Leviticus 16:21, 22, signify faith. Because man is regenerated by the Lord by the truth of faith, and consequently, his sins are removed and cast into hell, therefore it is said that "Aaron made the goat bear upon him all the iniquities of the children of Israel unto the land of separation, or into the wilderness." From correspondences, a goat signifies the natural man. The goat which was sacrificed, as in Leviticus 16:5-10, signifies the natural man regarding a part purified, and the goat which was sent into the wilderness regarding the natural man not purified.

7997. The Passover supper represented the groups of angels in heaven living in association with one another according to their forms of good and truths, see above in 7836, 7996. And since it represented those groups it was decreed not only that each household should be together by itself to eat it on that occasion but also that none should be associated with them except those who could represent togetherness in love characteristic of heavenly communities. All others were to be set apart. Those to be set apart were 'foreigners', for these meant people who were not in possession of the Church's goodness and truth. Those to be set apart also 'strangers' and 'hired servants', since these represented people prompted by natural inclination alone and people seeking material gain who would make a show of doing what was good and true. None of these can be integrated among the angels in heaven. But they are allowed to wander around during the initial period after their arrival in the next life, before they undergo the stages of vastation of good and truth. When during that initial period they approach any heavenly community and sense the sphere of holiness emanating from the truth belonging to the good of innocence, meant by 'the blood of the Passover lamb', 7846, 7877, they can go no further but in fear and loathing make a hasty retreat.
