Meaning
(1) Men may glorify God, that is, give to Him the worship and reverence which are His due (Isa 24:15, Isa 25:3, Ps 22:23, Dan 5:23; /APC Wisdom of Sirach 43:30, Mt 5:16, and generally in the Synoptic Gospels and in some other passages of the New Testament).
(2) God, Yahweh (Yahweh), glorifies His people, His house, and in the New Testament, His Son, manifesting His approval of them and His interest in them, by His interposition on their behalf (Isa 55:5, Jer 30:19; The Wisdom of Solomon 18:8; Wisdom of Sirach 45:3, Joh 7:39, and often in the Fourth Gospel).
(3) by a usage which is practically confined to the Old Testament, Yahweh glorifies Himself, that is, secures the recognition of His honor and majesty, by His direction of the course of history, or by His interposition in history, either the history of His own people or of the world at large (Lev 10:3, Isa 26:15, Ezek 28:22, Hag 1:8).
