Revelation 1:15

tn The precise meaning of the term translated “polished bronze” (χαλκολιβάνῳ, chalkolibanō), which appears nowhere else in Greek literature outside of the book of Revelation (see 2:18), is uncertain. Without question it is some sort of metal. BDAG 1076 s.v. χαλκολίβανον suggests “fine brass/bronze.” L&N 2.57 takes the word to refer to particularly valuable or fine bronze, but notes that the emphasis here and in Rev 2:18 is more on the lustrous quality of the metal.

tn Or “that has been heated in a furnace until it glows.”

tn Grk “sound,” but the idea is closer to the roar of a waterfall or rapids.
