21:18-21 Observe how the criminal is here described. He is a stubborn and rebellious son. No child was to fare the worse for weakness of capacity, slowness, or dulness, but for wilfulness and obstinacy. Nothing draws men into all manner of wickedness, and hardens them in it more certainly and fatally, than drunkenness. When men take to drinking, they forget the law of honouring parents. His own father and mother must complain of him to the elders of the city. Children who forget their duty, must thank themselves, and not blame their parents, if they are regarded with less and less affection. He must be publicly stoned to death by the men of his city. Disobedience to a parent's authority must be very evil, when such a punishment was ordered; nor is it less provoking to God now, though it escapes punishment in this world. But when young people early become slaves to sensual appetites, the heart soon grows hard, and the conscience callous; and we can expect nothing but rebellion and destruction.
18-21. If a man have a stubborn and rebellious son—A severe law was enacted in this case. But the consent of both parents was required as a prevention of any abuse of it; for it was reasonable to suppose that they would not both agree to a criminal information against their son except from absolute necessity, arising from his inveterate and hopeless wickedness; and, in that view, the law was wise and salutary, as such a person would be a pest and nuisance to society. The punishment was that to which blasphemers were doomed [Le 24:23]; for parents are considered God's representatives and invested with a portion of his authority over their children.
