7781. And every firstborn of beast. That this signifies the adulterated goods of faith, is evident from the signification of “firstborn,” as being faith; and from the signification of “beast,” as being the affections of good, and in the opposite sense the affections of evil (see n. 45, 46, 142, 143, 246, 714, 715, 719, 776, 2179, 2180, 3519, 5198). That “beasts” have this signification is from the representatives in the other life (n. 3218). Therefore also such things were signified by them in sacrifices (n. 2180, 2805, 2807, 2830, 3519). As “beasts” had this signification, therefore by “the firstborn of beast” is signified the good of truth, in this case adulterated, because belonging to the Egyptians, who perverted all truths and goods by applications to evil uses.
