For it is evident enough that words have no effect but on those that understand them; and then they have no other but to signify the intentions or passions of them that speak; and thereby produce hope, fear, or other passions or conceptions in the hearer. Therefore when a rod seemeth a serpent, or the waters blood, or any other miracle seemeth done by enchantment; if it be not to the edification of God’s people, not the rod, nor the water, nor any other thing is enchanted; that is to say, wrought upon by the words, but the spectator. So that all the miracle consisteth in this, that the enchanter has deceived a man; which is no miracle, but a very easy matter to do.
