1 Thessalonians 5:3

ὅταν γὰρ λέγωσιν, Εἰρήνη καὶ ἀσφάλεια, τότε αἰφνίδιος αὐτοῖς ἐφίσταται ὄλεθρος, ὥσπερ ἡ ὠδὶν τῇ ἐν γαστρὶ ἐχούσῃ, καὶ οὐ μὴ ἐκφύγωσιν.

otan gar legōsin, Eirēnē kai asphaleia, tote aiphnidios aytois ephistatai olethros, ōsper ē ōdin tē en gastri echoysē, kai oy mē ekphygōsin.

King James Version (KJV)

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.

Modern English

While people are saying, Peace and safety, destruction will come on them suddenly, as labor pains on a pregnant woman, and they will not escape.
