1 Thessalonians 5:3 in the King James Version
For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
Context
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.
4 But you, brothers, aren’t in darkness, that the day should overtake you like a thief.
