Leviticus 20 - G. Campbell Morgan's Exposition on the Whole Bible

Once more we have a repetition of laws already enunciated with the same persistent thought of responsibility. In this section we find the death sentence associated with certain forms of disobedience, and thus the fact of responsibility is lifted into a yet more clearly defined importance and lays a new and startling emphasis on the absolute authority of God. All the words which had thus been uttered for conditioning life were definite and positive laws. They were infinitely more than general messages of advice and direction. To disregard them was not merely unwise, it was positively penal a and must be visited with actual punishment, and in certain cases with the death penalty.
