9287. The feast of unleavened things shalt thou keep. That this signifies worship and thanksgiving on account of purification from falsities, is evident from the signification of a “feast,” as being the worship of the Lord and thanksgiving on account of liberation from damnation (of which just above, n. 9286); and from the signification of “unleavened things,” as being purification from falsities; for by what is fermented is signified falsity, and therefore by what is unfermented or unleavened is signified good purified from falsities (n. 2342, 8058). (Concerning this feast, which was also called the “passover,” see below, n. 9292, 9294)

9292. Because in it thou camest forth out of Egypt. That this signifies liberation from infestation by falsities, is evident from what has been said and shown about the going forth of the sons of Israel out of Egypt, in n. 7107, 7110, 7126, 7142, 7220, 7228, 7240, 7278, 7317, 8866, 9197, where it may be seen that by the sojourning of the sons of Israel in Egypt was signified the infestation by the infernals of the spiritual, that is, of those who were of the Lord’s spiritual church, and their protection by the Lord; and that by their “going forth out of Egypt” was signified their liberation from that infestation; in commemoration of which was instituted the passover, which was the feast of unleavened things (n. 7093, 7867, 7995).
