Deuteronomy 19:19 Meaning and Commentary

Deuteronomy 19:19

Then shall ye do unto him as he had thought to have done unto
his brother
Inflict the same fine or punishment on him he thought to have brought his brother under by his false testimony of him; whether any pecuniary fine, or whipping and scourging, or the loss of a member, or the value of it, or death itself; whether stoning, strangling, burning, or killing with the sword: though, in the case of accusing a priest's daughter of adultery, as Jarchi observes, such were not to be burnt, as would have been her case if proved, but strangled:

so shalt thou put the evil away from among you;
the evil man that bears a false testimony of his brother, or the guilt of sin which would be incurred by conniving at him.

Deuteronomy 19:19 In-Context

17 then both parties involved in the quarrel must stand in the Presence of God before the priests and judges who are in office at that time.

18 The judges must conduct a careful investigation; if the witness turns out to be a false witness and has lied against his fellow Israelite,

19 give him the same medicine he intended for the other party. Clean the polluting evil from your company.

20 People will hear of what you've done and be impressed; that will put a stop to this kind of evil among you.

21 Don't feel sorry for the person: It's life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
