The Bible actually has quite a bit to say about knowing another’s thoughts.

So the king of Israel sent word concerning the place of which the Holy Man had warned him.This kind of thing happened all the time.The king of Aram was furious over all this. He called his officers together and said, “Tell me, who is leaking information to the king of Israel? Who is the spy in our ranks?”  But one of his men said, “No, my master, dear king. It’s not any of us. It’s Elisha the prophet in Israel. He tells the king of Israel everything you say, even what you whisper in your bedroom.” - 2 Kings 6
