That this signifies their mutual thoughts, is evident from the signification of “saying,” as being to perceive and to think (n. 3395); and from the signification of “a man to his brother,” as being mutually. It was a customary form of speech with the ancients to say “a man to his brother” when what is mutual was signified; for the reason that a “man” signified truth (n. 3134, 3459), and a “brother” good (n. 4121), between which there intervenes a most intimate mutual relation; for the conjunction of truth with good and of good with truth takes place mutually and reciprocally (n. 2731).
