Leviticus 18:23

23. With any beast Let him who denies the inherent depravity of man study this prohibition. This prohibition implies the sacredness and dignity of human nature, inasmuch as the abomination was punished by death. In Egypt women publicly submitted themselves to goats. Nor has unregenerate nature entirely outgrown its dreadful downward tendency. In modern Egypt men lie even with female crocodiles. ( Sonnini, R. 11, p. 330.) The heathen generally have no moral abhorrence for this crime. The Revised Statutes of Massachusetts, a foremost Christian State, contains this law: “Whoever commits the abominable and detestable crime against nature, either with mankind or with any beast, shall be punished in the State prison not exceeding twenty years.”
