Let's look at God's opinion of false witnesses; those who accuse others of doing something wrong, when they didn't.
Deuteronomy 19
15 One witness is not enough to convict anyone accused of any crime or offense they may have committed.
A matter must be established by the testimony of two or three witnesses.
16 If a malicious witness takes the stand to accuse someone of a crime,
17 the two people involved in the dispute must stand in the presence of the Lord before the priests and the judges
who are in office at the time.
18 The judges must make a thorough investigation,
and if the witness proves to be a liar, giving false testimony against a fellow Israelite,
19 then do to the false witness as that witness intended to do to the other party. You must purge the evil from among you.
20 The rest of the people will hear of this and be afraid, and never again will such an evil thing be done among you.
21 Show no pity: life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
The term used here is 'malicious witness', also called a false witness.
Do you see what God said to do when a false witness is discovered?
God said to give them the punishment the accused person would have received, had they been found guilty.
And, I believe that when lying adults stand before God on the Judgement Day, this is what will happen to them.
The liars will get the punishment they tried to put an innocent person.
You see, it's hard to lie for yourself without falsely accusing others.
As an adult, when two cars get in a car wreck, if the guilty person says he didn't do it,
then he is automatically blaming the innocent person.
Always take the blame if you did it.
Never accept the blame if you didn't do it.
Share the blame when the blame should be shared.
