1 Thessalonians 5:2 in the King James Version
For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
Context
1 But concerning the times and the seasons, brothers, you have no need that anything be written to you.
2 For you yourselves know well that the day of the Lord comes like a thief in the night.
3 For when they are saying, “Peace and safety,” then sudden destruction will come on them, like birth pains on a pregnant woman. Then they will in no way escape.
