Romans 2:15 in the 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;)
Context
14 (for when Gentiles who don’t have the law do by nature the things of the law, these, not having the law, are a law to themselves,
15 in that they show the work of the law written in their hearts, their conscience testifying with them, and their thoughts among themselves accusing or else excusing them)
16 in the day when God will judge the secrets of men, according to my Good News, by Jesus Christ.
