If prophets or those who divine by dreams appear among you and promise you omens or portents, and the omens or the portents declared by them take place, and they say, “Let us follow other gods” (whom you have not known) “and let us serve them,” you must not heed the words of those prophets or those who divine by dreams; for the LORD your God is testing you, to know whether you indeed love the LORD your God with all your heart and soul.
