An instrument used for burning incense.

And the smoke of the incense, which came with the prayers of the saints, ascended up before God out of the angel's hand. And the angel took the CENSER, and filled it with fire of the altar, and cast it into the earth: and there were voices, and thunderings, and lightnings, and an earthquake. ( Revelation 8:4-5 )
