Revelation 11:3-12 is about 2 witnesses, are they men or angels ? The verse that answers this question is verse 11. The breath of life proves they are men because angels do not have the breath of life. Some say these 2 are Moses and Elijah or Enoch in some combination but the truth about the dead shows this is not true. My guess is they are of the Laodicea church and this because they are martyred along with all other Laodiceans.
