What Does 1 Thessalonians 5:2 Mean in the King James?

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

1 Thessalonians 5:2 · KJV

The analysis reads the King James wording.

King James Version The King James Version, first published in 1611. Selah Verse shows the standard text.

THE KEY

You know the arrival’s manner precisely, though its hour remains hidden.

THE MEANING

You recognize the shape of what you cannot place on a calendar: the day of the Lord comes suddenly, like a thief in the night. Its manner is knowable; its hour is not given.

WHAT THIS UNDOES

The verse undoes the belief that true knowledge must include a date: here, knowing means recognizing the suddenness of the arrival, not possessing its schedule.

THE ROOT

οἴδατε

oidate

GROWS FROM

εἰδ

eid

See, perceive; ⁨οἶδα⁩ is historically a perfect form meaning “have seen,” hence “know.”

“know” in this verse is oidate. The knowing here carries the feel of recognition: you see the pattern clearly. What you recognize is how the day arrives, not when it will arrive.

ALSO GROWS

oida: Know, recognize

οἶδα

This is the verb behind the verse’s “you know”; its history links knowing with having seen.

eidon: Saw, perceived

εἶδον

This related form makes visible the connection between seeing and knowing that English leaves hidden.

κλέπτης

kleptēs

GROWS FROM

κλεπ-

klep-

Steal, take secretly.

“thief” in this verse is kleptēs. The comparison gives the arrival the character of something that comes without notice. The image makes suddenness concrete: the day does not announce its approach.

ALSO GROWS

kleptō: Steal

κλέπτω

The verb names the action behind “thief,” sharpening the image of an arrival that takes place unannounced.

klopē: Theft

κλοπή

This noun preserves the same root in the idea of taking; it connects the verse’s image with secrecy and suddenness.

ἀκριβῶς

akribōs

GROWS FROM

ἀκριβ-

akrib-

Exact, precise, careful.

“Perfectly” describes the clarity of what you know, not possession of a timetable. The sentence holds precision and unpredictability together: you know the pattern exactly, while the hour stays hidden.

ALSO GROWS

akribēs: Exact, accurate

ἀκριβής

This related adjective shows the precision carried by “perfectly.”

akriboō: Examine or determine carefully

ἀκριβόω

The verb shares the root’s careful precision, underscoring that the knowledge concerns the manner of arrival.

THE PATTERN

The day arrives without a schedule to master; it is recognized by its suddenness.

But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up.

Matthew 24:43 · KJVThe thief image turns the unknown hour into a concrete arrival that cannot be scheduled in advance.

But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.

2 Peter 3:10 · KJVThe same comparison joins the day of the Lord to an arrival that gives no advance notice.

Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.

Revelation 3:3 · KJVThe verse makes the hidden hour explicit while repeating the thief-like arrival.

THE THREAD

But ye, brethren, are not in darkness, that that day should overtake you as a thief.

1 Thessalonians 5:4 · KJV

The next verse opens the image further: the day comes like a thief, yet the reader is not in darkness. The passage distinguishes the day’s sudden arrival from being left without recognition.
