Deuteronomy 13:2-3

2and a  the sign or wonder that he tells you comes to pass, and if he says, ‘Let us go after other gods,’ which you have not known, ‘and let us serve them,’ 3you shall not listen to the words of that prophet or that dreamer of dreams. For the  Lord your God b  is testing you, to know whether you love the  Lord your God with all your heart and with all your soul.
