For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
Ver. 2. The day of the Lord] That day, by a specialty, Luke 21:34, that great day, Revelation 6:17, that day of the declaration of God's just judgment, Romans 2:5; Romans 2:16, that day of Christ, 2 Thessalonians 2:2, of God, 2 Peter 3:12, wherein he will show himself to be God of gods and Lord of lords.
As a thief in the night] Who giveth no warning, Matthew 24:43. See Trapp on " Mat 24:43 "
