Deuteronomy 13:1-4

1If a prophet, or one who foretells by dreams, appears among you and announces to you a sign or wonder,

2and if the sign or wonder spoken of takes place, and the prophet says, “Let us follow other gods” (gods you have not known) “and let us worship them,”

3you must not listen to the words of that prophet or dreamer. The Lord your God is testing you to find out whether you love him with all your heart and with all your soul.

4It is the Lord your God you must follow, and him you must revere. Keep his commands and obey him; serve him and hold fast to him.
