Deuteronomy 13:1-4

Prophets or those who tell the future with dreams might come to you and say they will show you a miracle or a sign. The miracle or sign might even happen, and then they might say, “Let’s serve other gods” (gods you have not known) “and let’s worship them.” But you must not listen to those prophets or dreamers. The LORD your God is testing you, to find out if you love him with your whole being. Serve only the LORD your God. Respect him, keep his commands, and obey him. Serve him and be loyal to him.
