Behold, I am coming soon: for Behold see 1.7; and see comment at Rev. 22.7, above. By its use of quotation marks, Revised Standard Version intends to show that someone other than the writer is speaking. It is better to indicate that Jesus is the speaker, as Good News Translation, Bible en français courant, and Nova Tradução na Linguagem de Hoje do.
Bringing my recompense, to repay every one: this applies to all, the righteous and the evil alike. So my recompense may be reward (see 11.18) or it may be punishment (see 18.6). Another way of expressing this is “I am coming to either reward or punish all people for what they have done.”
For what he has done: see 2.23, “as your works deserve”; 20.12, 13.
