John Gill Bible Commentary

And it be told thee, and thou hast heard of it, and inquired diligently,.... A report of this kind was not to be neglected; though it was not to be concluded upon as certain by hearsay, it was to be looked into, and the persons that brought it thoroughly examined; so the Targum of Jonathan,"and inquired the witnesses well,''what proof and evidence they could give of the fact, who the persons were, when and where, and in what manner the sin was committed: and, behold, it be true, and the thing certain; upon examining the witnesses the case is plain and out of all question: that such abomination is wrought in Israel; to do it in any country was abominable, but much more so in the land of Israel, among the professing people of God, who had the knowledge of the true God, and had had so many proofs of his deity, his power and providence, as well as received so many favours and blessings from him, and had such laws and statutes given them as no other people had.
