Revelation 2:16
Therefore repent. If not, I will come to you soon and war against them with the sword of my mouth.
Revelation 1:12-16
Then I turned to see the voice that was speaking with me. And having turned, I saw seven golden lampstands, and among the lampstands was One like the Son of Man, dressed in a long robe, with a golden sash around His chest. The hair of His head was white like wool, as white as snow, and His eyes were like a blazing fire. His feet were like polished bronze refined in a furnace, and His voice was like the roar of many waters. He held in His right hand seven stars, and a sharp double-edged sword came from His mouth. His face was like the sun shining at its brightest.
