8267. And song is Jah. That this signifies that everything of faith and of the consequent glory is from the Divine truth which is from Him, is evident from the signification of a "song" when said concerning Jehovah, as being a glorification of the Lord (see above, n. 8261); but when concerning man, as here, as being the glory which is from faith, thus faith from which is glory; for everything of glory that pertains to man is from faith in the Lord, because faith which is faith is from the Lord, and thus the Lord is in the faith, consequently so is the glory itself. That the glory of man is from faith is also because the Divine truth, from which and through which is faith, appears before the eyes of the angels as light, and also as brightness and a beam of light. This beam of light, together with the magnificences of heaven that are from the light, is called "glory," which accordingly is nothing else than Divine truth, thus faith.
 That "Jah" denotes the Divine truth proceeding from the Divine Human of the Lord, is because "Jah" is from "Jehovah" and is called "Jah" because it is not being, but coming-forth from being; for Divine truth is coming-forth, but Divine good is being (n. 6880); and consequently it is said "Jah is my song," because by "song" is signified the faith which is of Divine truth. By "Jah" is signified Divine truth in David also:
Sing ye to God, praise ye His name; extol Him that rideth upon the clouds by His name Jah, and exult ye before Him (Ps. 68:4);
where "to praise and extol God by His name Jah" denotes by means of Divine truth. Again in the same:
In distress I called on Jah; Jah answered me in breadth; Jehovah helped me; Jah is my strength and song; I shall not die, but live, and declare the works of Jah; I will enter through the gates of righteousness, and I will confess Jah (Ps. 118:5, 13, 14, 17, 19);
here "Jah" denotes the Lord as to Divine truth; in like manner "Jah" in "Hallelu-Jah" (Ps. 105:45; 106:1, 48; 111:1; 112:1; 113:1, 9; 115:17, 18; 116:29).
