Expositor's Bible Commentary Commentary Revelation 14:5

"And in their mouth was found no lie: they are without blemish." — Revelation 14:5 (ASV)

The “lie” that brings “blame” refers to the blasphemy of the beast worshipers who deny the Father and the Son and ascribe vitality to the beast by believing his heresies and worshiping his image (21:27; 22:15; Romans 1:25; 2 Thessalonians 2:9–11; 1Jn 2:4, 21-22, 27).
