And I John saw these things, and heard them,.... He was both an eye and an ear witness; some things he saw, and others he heard; and to render his testimony the more authentic, he puts his name to it; and he being an apostle of Christ, and a man of great sincerity and probity, is to be believed.
And when I had heard and seen; the things related in this book, being amazed at them, and filled with joy on account of many of them, and firmly believing the whole as coming from God:I fell down to worship before the feet of the angel which showed me these things.
