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 a false witness testifies against someone, accusing him of a crime,

17 both parties to the dispute must stand in the presence of the LORD, before the priests and judges who are in office at that time.

18 The judges shall investigate thoroughly, and if the witness is proven to be a liar who has falsely accused his brother,

19 you must do to him as he intended to do to his brother. So you must purge the evil from among you.

20 Then the rest of the people will hear and be afraid, and they will never again do anything so evil among you.
