John says a sharp two-edged sword came from the mouth of the Son of Man figure Revelation 1:16. The description is part of the vision of Jesus among the lampstands Revelation 1:12–16.
In Revelation 1:12–16 John turns toward the voice addressing him and sees seven golden lampstands. Standing among them is a humanlike figure described with vivid, symbolic features: long robe and golden sash, white hair, blazing eyes, radiant face, and a thunderous voice. The figure holds seven stars, and a sharp double-edged sword comes from his mouth. This scene follows the opening lines where John introduces himself and reports receiving a message while on Patmos (1:9–11). The voice instructs him to write what he sees and send it to seven churches; John then turns and the vision begins.
John’s vision is triggered by a voice; when he turns, what he sees is not a normal speaker but a symbolic scene: seven golden lampstands with a humanlike figure “in the midst” of them (verses 12–13).
A common mistake is to turn the wording into a slogan. The better reading keeps the phrase tied to the passage, the speaker, and the problem the book is addressing.
Start with Revelation 1:16, then read the surrounding section so the answer stays connected to the passage's flow.
16He had seven stars in his right hand. Out of his mouth proceeded a sharp two-edged sword. His face was like the sun shining at its brightest.
