Darby Translation

¹⁸ If a man have an unmanageable and rebellious son, who hearkeneth not unto the voice of his father, nor unto the voice of his mother, and they have chastened him, but he hearkeneth not unto them;

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;
