King James wording
King James Version
For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.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 householder knew in what watch the thief comes, he would stay awake and would not let his house be dug through.But the day of the Lord will come as a thief in the night, in which the heavens shall pass by with a rushing roar, and the building blocks shall melt in scorching heat; the earth also, and the works in it, shall be burned down.Remember, then, how you have taken hold and heard. Guard it, and turn. If you do not stay awake, I will come upon you as a thief, and you will not know what hour I will come upon you.THE THREAD
But you, brothers, are not in darkness, so that the day would seize you like a thief.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.
