Deuteronomy 21:18-21 -

If a son was refractory and unmanageable by his parents, if, given to sensual indulgence, he would yield neither to reproof nor to chastisement,—the parents were to lay hold on him, and lead him to the ciders of the town, sitting as magistrates at its gates, and there accuse him of his evil ways and rebelliousness. The testimony of the parents was apparently held sufficient to substantiate the charge, and this being received by the elders, the culprit was to be put to death by stoning.
