Jehovah's Witnesses use this verse
(along with 1 Timothy 5:19 and Matthew 18:16)
to justify their refusal to report or investigate incidents of child molestation unless two or three
JWs have witnessed the event. If witnesses do not come forward (and they are
discouraged from doing so since it would embarrass the organization), then the
victim is told to be quiet about it -- or risk being disfellowshipped. 19:15
When someone commits "a sin worthy of death" that person is "accursed of God" and should be hung on a tree. But should the accursed person be killed first by stoning and
then hung on a tree or be killed by hanging on a tree -- that is, by crucifixion?
I'll leave that for the Bible scholars to decide.
The important thing is to make sure you take the accursed dead body down before nightfall. Leaving dead bodies on trees all night is just nasty. Too nasty even for a
very nasty God. 21:22-23
