Deuteronomy 21:19
Then shall his father and his mother lay hold on him, and bring him out unto the elders of his city, and unto the gate of his place; Then shall his father and his mother lay hold on him, and bring him out unto the elders of his city, and unto the gate of his place;
The law concerns a persistently stubborn and rebellious son who will not obey his father and mother. His refusal continues even after his parents have chastened him. Both the father and the mother are to lay hold on him and bring him out to the elders of his city at the gate of his place.
This step brings the case before Israel's rulers and leaders, where his conduct is formally reported and judged. The rebellion includes refusal to be restrained in appetite, gorging and gluttony, which is treated alongside drunkenness and shows the seriousness of uncontrolled appetite.
Such an offender is regarded as hopeless and harmful to others. The verses that follow give the judgment, whose purpose is to put evil away and to warn Israel.
