"As travail upon a woman with child"

But of the times and the seasons, brethren, ye have no need that I write unto you.

For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.

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.

1 Thessalonians 5:1-3
