Revelation 6:11

And white robes were given unto every one of them; and it was said unto them, that they should rest yet for a little season, until their fellowservants also and their brethren, that should be killed as they were, should be fulfilled.

Ver. 11. And white robes] Their innocence was cleared, and their persecutors convinced. God would speak for them in the hearts of their greatest enemies.

Until their fellowservants also] We doubt not, saith a learned interpreter here (Mr Forbes), but that the crowned saints do in general know the afflicted condition of the Church militant, and do wish them deliverance; but our special necessities and occurrences of particular persons they cannot know. Brother Bradford, said Bishop Ridley, a little before he was offered up, so long as I shall understand that thou art in thy journey, by God's grace I shall call upon our heavenly Father to set thee safely home; and then, good brother, speak you for the remnant that are to suffer for Christ's sake, according to that thou then shalt know more clearly. (Acts and Mon.) But this is to be taken with a grain of salt.

That should be killed] Under Licinius, Julian the Apostate, and the Arian emperors.
