To smite either father or mother, in a manner which indicated either contempt or malice, or left marks of violence, was deemed a proof of so ungrateful and unnatural a disposition, that no provocation was admitted as an excuse, but the offence was made capital: nay, he who cursed his father or mother, who uttered imprecations, ill wishes, or revilings, against a parent, was included in the same sense; though few crimes were made capital by the law of Moses. The law of God, as delegated to parents is honoured when they are honoured, and despised when they are despised, and to rebel against the lawful exercise of this authority is rebellion against God. - Rev. T. Scott Deu 21:18-21, Deu 27:24, Pro 30:11, Pro 30:17, 1Ti 1:9
