Charles Ellicott Commentary Revelation 22:20

"He who testifieth these things saith, Yea: I come quickly. Amen: come, Lord Jesus." — Revelation 22:20 (ASV)

He which testifieth these things . . .—Better, He saith, who testifieth these things, Yea, I am coming quickly. We have here the final witness; it is in the words of the faithful and true witness Himself. It is the answer to the repeated cry, “Come;” it is the warning to those who forget Him; it is introduced with the emphatic yea! Yea, I am coming quickly. The answer breaks forth in prayer from the prophet’s lips—Amen. (We must omit “even so”) Come, Lord Jesus. The prophet is the mouthpiece of the Church; his desire is one with the desire of all who love Christ’s appearing.
