And behold, I come quickly (κα ιδου ερχομα ταχυ). Christ is the speaker, either through this angel or more probably directly from Christ without introduction as in verses Revelation 22:12; Revelation 22:16. About Christ coming quickly see Revelation 2:5; Revelation 2:16; Revelation 3:11; Revelation 16:15, and already in Revelation 1:2. Once more we must recall that ταχυ and εν ταχε are according to God's time, not ours (2 Peter 3:8).

Blessed (μακαριος). This beatitude is like in substance the first (Revelation 1:3) and is in Christ's own words like the one in Revelation 16:15. This book is here called a "prophecy" (προφητειας) as in verses Revelation 22:10; Revelation 22:18; Revelation 22:19. It is Christ's revelation from God, a direct message from God. Part of it is prediction of doom on Christ's enemies, but most of it is a comforting picture of final triumph and bliss for the faithful in a time of great distress and persecution.

Rev 22:8

And I John (Καγω Ιωαννης). Here John the Seer is the speaker. He had already given his name (Revelation 1:1; Revelation 1:4; Revelation 1:9). Here he claims to be the "one who hears and sees these things" (ο ακουων κα βλεπων ταυτα).

I fell down to worship (επεσα προσκυνησα). Second aorist active indicative of πιπτω (with -α form) and the first aorist active infinitive of purpose of προσκυνεω. It was a natural, though a wrong, thing to do, especially after Christ's own voice followed that of the angel "which shewed me these things" (του δεικνυοντος ταυτα). Genitive singular of the articular present active participle of δεικνυω. Cf. Revelation 1:1; Revelation 4:1; Revelation 17:1; Revelation 21:9; Revelation 22:1; Revelation 22:6.
