Re. 22:16 Just as John gave his signature, and guarantee in v. 8; so here Jesus attests and guarantes the truth John has seen and heard. 1) Mediated by angesl b) unto the churches. 3) Historically, Jesus is that Christ, the offspring of David, the expected Messiah, and this event (Jerusalem’ s fall) is the guarantee of that truth (Matt. 1:1; cf. Isa. 11:11; Rev. 5:5)
