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.)
