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 This is what you must do whenever a witness takes the stand to accuse a person falsely of a crime.

17 The two people involved must stand in the LORD's presence, in front of the priests and judges who are serving at that time.

18 The judges must make a thorough investigation. If it is found that the witness lied when he testified against the other Israelite,

19 then do to him what he planned to do to the other person. You must get rid of this evil.

20 When the rest of the people hear about this, they will be afraid. Never again will such an evil thing be done among you.
