Revelation 22:6-9

Revelation 22:6-9. And he said unto me, These sayings are faithful and true: and the Lord God of the holy prophets sent his angel to shew unto his servants the things which must shortly be done. Behold, I come quickly: blessed is he that keepeth the saying of the prophecy of this book. And I John saw these thing, and heard them. And when I had heard and seen, I fell down to worship before the feet of the angel which shewed me these things. Then saith he unto me, See thou do it not: for I am thy fellow servant, and of thy brethren the prophets, and of them which keep the sayings of this book: worship God.

It was a pardonable mistake that John made, but it was a mistake, for even the highest angel in heaven must not be accorded the worship that is due to God alone.
