464. Verse 12. Saying, Amen, signifies the Lord in relation to Divine truth from Divine good. This is evident from the signification of "Amen," as being truth; and because the Lord is truth itself (as He teaches in John 14:6), "Amen" in the highest sense signifies the Lord in relation to Divine truth; here this is signified by "Amen" because it is spoken by the angels of the three heavens to the Lord. "Amen" here stands at the beginning of what is said and also at the end to signify that the Lord in relation to Divine truth from Divine good is in things first and in ultimates, or that the Lord Himself is the First and the Last; for Divine truth united to Divine good is the Lord in the heavens, for this is the Divine proceeding from which are all things of heaven, and heaven itself (as may be seen in the work on Heaven and Hell, n. 13, 126-140, 275. That to be in things first and in ultimates signifies to be in all things, may be seen above, n. 41, 417, and in Arcana Coelestia, n. 10044, 10329, 10335; and that "Amen" signifies the Lord in relation to Divine truth, see above, n. 228).
