John Calvin on Deuteronomy 18:22

22. The prophet hath spoken it presumptuously. He not only condemns the folly and vanity of those who advance their own inventions in the place of God’s commands, but also their arrogance; since doubtless, this is impious and intolerable audacity, to set forth the offspring of man’s earthly brain as if it were a divine revelation. And on this ground it is that their impiety is detestable, who fill the air with the fumes of their revelations in order to alarm the simple. Wherefore, he adds, that they should “not be afraid” of such a prophet; because, as nothing can be more arrogant than the ministers of Satan, they confidently utter their boastings, by which we may be easily moved and even overwhelmed, unless we had this buckler to protect us, viz., that their terrific noise may be safely despised. This doctrine is now-a-days very useful for us. We know how insolently the Papists boast of the Catholic Church; of the Apostolic See; how fiercely they rage in Peter’s name; how impetuously they fulminate their curses and anathemas; but, when it is ascertained that whatever they put forward as revelations of the Spirit are but the empty figments of men, it will be easy to dispel those terrors which flow from this same fountain of presumption.

Leviticus 18

Leviticus 18:21

21. And thou shalt not let any of thy seed pass through the fire to Molech, neither shalt thou profane the name of thy God: I am the Lord.

21. E semine tuo non dabis quod trajiciatur coram Moloch: neque profanabis nomen Dei tui: Ego Jehova.

Leviticus 19

Leviticus 19:26, 31

26. Neither shall ye use enchantment, nor observe times.

26. Non augurabimini, neque divinationi eritis intenti.

31. Regard not them that have familiar spirits, neither seek after wizards, to be defiled by them: I am the Lord your God.

31. Non respicietis post Pythones, et ariolos non inquiretis: ut polluamini in ipsis. Ego Jehova Dens vester.
