Luke 17:34

I say unto you, In that night, there shall be two men on one bed; and the one shall be taken, and the other shall be left. There shall be two women grinding together; ... Two men shall be in the field; the one shall be taken, and the other left.

In that night ... contrasts with "in that day" (Luke 17:31); and some of the ancient skeptics scoffed at the idea that Jesus' coming could be both at night and in the daytime also; but present knowledge of the fact that it is always night on part of the earth, and always day on the other part, has eliminated the question from the writings of modern critics.

Shall be taken ... shall be left ... Which of these refers to the saved, which to the unsaved? From 1 Thessalonians 4:13-18, it would appear that the saved are the ones who shall be "taken." Harrison, however, cautioned that "TAKEN is often applied to saints, but it may refer to the gatherings of offenders to judgment (Matthew 13:42)."[38] The evidence, however, favors the other view.
