Try this explanation:
A revelation by Jesus Christ, which God gave him, to show his slaves the things that must shortly take place. And he sent his angel and presented it in signs through him to his slave John, 2who bore witness to the word God gave and to the witness Jesus Christ gave, yes, to all the things he saw. 3Happy is the one who reads aloud and those who hear the words of this prophecy and who observe the things written in it, for the appointed time is near.
