King James wording
King James Version
Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;)THE KEY
The instruction is pictured as an inner inscription: conscience bears witness to it while the thoughts argue both sides.
THE MEANING
Your conscience bears witness to an inwardly registered moral claim, while your thoughts can accuse or defend one another. The verse presents these as distinct parts of your inner life, not as one unquestionable voice.
WHAT THIS UNDOES
It undoes the belief that moral recognition comes only from an outside command or another person’s verdict; the verse locates a witness within you.
THE ROOT
συνείδησις
syneidēsis
GROWS FROM
οἶδα (oida), joined with σύν (syn)
To know or perceive together; shared inward knowing.
The Greek word for conscience carries the sense of knowing-with, more than a passing feeling. The verse gives this inner awareness the role of witness, while the thoughts themselves bring accusation or defense.
ALSO GROWS
synoida: Know with, share awareness.
σύνοιδα
This related verb brings out the shared-knowing sense behind conscience as an inward witness.
oida: Know, perceive.
οἶδα
This root helps show conscience as a kind of inner knowing, not merely an emotion.
γραπτόν
grapton
GROWS FROM
γράφω
graphō
Write, inscribe.
“written” in this verse is grapton. The verse pictures the instruction as an inscription in the heart. Its inward presence is paired with the conscience’s witness, so the moral claim is more than an external rule being recited.
ALSO GROWS
graphē: Writing, document.
γραφή
This branch keeps the image of something made visible through writing.
gramma: Written mark, letter.
γράμμα
A written mark is a trace left behind, echoing the verse’s image of instruction inscribed within.
συμμαρτυρούσης
symmartyrousēs
GROWS FROM
μαρτυρέω
martyreō
Testify, give witness.
“bearing witness alongside” in this verse is symmartyrousēs. The conscience testifies, while the thoughts accuse or defend. The verse distinguishes the inner witness from the arguments being weighed, rather than treating every thought as the same voice.
ALSO GROWS
martys: Witness.
μάρτυς
This branch names the one who testifies, clarifying the conscience’s role in the verse.
martyria: Testimony, witness.
μαρτυρία
This branch names the testimony itself: the conscience gives witness as the thoughts make their case.
THE PATTERN
What is held inwardly becomes visible through the heart’s inscription and the conscience’s witness.
Do not let faithful love and truth let go of you. Bind them around your neck. Write them on the tablet of your heart.But this is the covenant I will cut with the house of Israel after those days, declares the LORD. I will set my instruction within them, and write it upon their hearts. And I will be their God, and they shall be my people.You are made visible as the letter of the Anointed One, served by us, written not with ink but with the breath of the living God, not on tablets of stone but on tablets of flesh in the heart.THE THREAD
You are made visible as the letter of the Anointed One, served by us, written not with ink but with the breath of the living God, not on tablets of stone but on tablets of flesh in the heart.Both verses use the Greek γράφω (graphō, write) word-family: Romans calls the instruction γραπτόν (grapton, written), while Corinthians pictures it as written in the heart. The shared root lets the conscience’s witness appear as a response to an inward inscription.
