Revelation 9

Revelation 9 is the ninth chapter of the Book of Revelation or the Apocalypse of John in the New Testament of the Christian Bible. The book is traditionally attributed to John the Apostle, but the precise identity of the author remains a point of academic debate. In this chapter, the next two angels' trumpets are sounded, following the sounding of the first four trumpets in chapter 8. These two trumpets and the final trumpet, sounded in chapter 11, are sometimes called the "woe trumpets".

The original text was written in Koine Greek. This chapter is divided into 21 verses.

Some early manuscripts containing the text of this chapter are among others:

English nonconformist Moses Lowman explains that "stars, in the language of prophecy, signify angels.

"The key to the bottomless pit" (Biblical Greek: ἡ κλεὶς τοῦ φρέατος τῆς ἀβύσσου, romanized: hē kleis tou phreatos tēs abyssou) is translated as "the key to the shaft of the Abyss" in the New International Version.

These locusts are 'a demonized version of the army of locusts in Joel 2:1–11'.

Early Methodist theologian Joseph Benson says that this instruction "demonstrates that they were not natural but symbolical locusts."

The Vulgate adds a Latin equivalent, Exterminans, which the Wycliffe Bible explains as "Destroyer". The latter also describes the angel as "the angel of deepness".
