Cross Examining Witnesses in the Old Testament

When the bible got put into the commoners language, the common person's language, these christians are now reading the bible. And they're goingum cross examination. These people sos you had to have witnesses. If a witness lies in court, they're suposed to get the punishment that would have been given to the accused. So i think its important beyond the case law examples in the old testament, where god specifically tells him how to execute justice,. he condemns false witnesses.
