Revelation 14:5

And in their mouth was found no guile: for they are without fault before the throne of God.

In their mouth was found no lie, for they are blameless.

And in their mouth was found no lie: they are without blemish.

and in their mouth there was not found guile, for unblemished are they before the throne of God.

And no lie was found in their mouths; they are blameless.
