נכון [AND, BEHOLD, IT BE TRUE, AND THE THING BE] CERTAIN — i.e. the evidence of the witnesses is in agreement (מְכֻוָּן‎)

והוגד לך ושמעת, “and you have been informed, and you will hear, etc.” The apparent repetition of the same thought means that whenever and wherever this accusation is brought to your attention you must immediately commence an investigation. As soon as you establish that the rumours you have heard are factual, you have to lead the guilty party to his or her place of execution where you will stone the guilty party to death.

ודרשת היטב, “you shall investigate thoroughly;” the numerical value of the word היטב equals the numerical value of the letters in the tetragrammaton, i.e. 26. It is as if the Torah had written “you shall investigate him in your capacity as the agent of Hashem.”

The testimony was consistent. Rashi is wants to make clear that you should not mistakenly explain that the verse means, “If in fact the report is authenticated and accurate” in reference to [his] idolatry. I.e. it is authenticated that he served idolatry. Therefore he explains, “The testimony was consistent, i.e., consistent in the mouths of the witnesses when you interrogated [them].

V. 4. יהגד לך ist die Aussage der Zeugen, ושמעת das gerichtliche Verhör derselben, ודרשת היטב die vorschriftsmäßige Ausforschung der Zeugen durch דרישות והקירות ובדיקות (siehe zu Kap. 13, 15).

נעשתה התועבה הזאת בישראל, “this abominable thing has indeed been carried out in (the land of) Israel;” the wording suggests that this legislation also applies in the Diaspora, seeing the word בקרבך which is used in the legislation of עיר הנדחת in conjunction with the word תועבה has been omitted here. The word בישראל at the end of this verse makes it clear that such conduct cannot be ignored in any Jewish community wherever it is located.
