Deuteronomy 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.

Deuteronomy 19:18 In-Context

16 If an unrighteous witness rise up against any man to testify against him of wrong-doing,

17 then both the men, between whom the controversy is, shall stand before Yahweh, before the priests and the judges who shall be in those days;

18 and the judges shall make diligent inquisition: and, behold, if the witness is a false witness, and has testified falsely against his brother;

19 then shall you do to him, as he had thought to do to his brother: so shall you put away the evil from the midst of you.

20 Those who remain shall hear, and fear, and shall henceforth commit no more any such evil in the midst of you.
