I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left.
All Commentaries on Luke 17:34 Go To Luke 17
Ambrose of Milan
AD 397
Two people in this world, which is very often compared with a field, are believers and unbelievers. One will receive the reward of their merits; therefore the faithful one is taken, but the faithless is left.
