Full Rev 3:7–13. Title echo: "he that hath the key of David" (3:7) re-cites both Rev 1:18 ("I have the keys of death and of Hades") and Isaiah's Eliakim oracle ("the key of the house of David will I lay upon his shoulder," Isa 22:22). City history: earthquake-prone (the AD 17 earthquake required imperial relief; the city was repeatedly rebuilt); the pillar imagery of v.
12 lands sharply against this background of instability. No rebuke: the second letter without one. Commendation: "a little power," kept Christ's word, did not deny his name (3:8). Promise: a pillar in the temple of my God, going out no more; the name of God, the name of the new Jerusalem, and Christ's own new name written on him (3:12).
