Devarim 19:18 Meaning and Commentary

Deuteronomy 19:18

And the judges shall make diligent inquisition
Into the case before them, into the nature of the evidence and proof that each witness brings for or against; so the Targum of Jonathan,

``the judges shall interrogate the witness, by whom these things are said, well;''

shall thoroughly examine the testimony given, and look carefully into it:

and, behold, if the witness be a false witness, and hath testified
falsely against his brother;
it appears plainly by full evidence that he has testified a falsehood of him.

Devarim 19:18 In-Context

16 If an ed chamas (malicious, false witness) rise up against any ish to testify against him that which is wrong;

17 Then both the men, between whom the controversy is, shall stand before Hashem, before the kohanim and the shofetim, which shall be in those days;

18 And the shofetim shall make diligent inquiry; and, hinei, if the witness be an ed sheker (false witness), and hath testified falsely against his brother;

19 Then shall ye do unto him, as he had thought to have done unto his brother: so shalt thou put harah away from among you.

20 And those which remain shall hear, and fear, and shall henceforth commit no more any such rah among you.
