Matthew 24:23

⁸He said, “Watch out that you don’t get led astray, for many will come in my name, saying, ‘I am he,’ ^[+] and, ‘The time is at hand.’ Therefore don’t follow them.

²³They will tell you, ‘Look, here!’ or ‘Look, there!’ Don’t go away or follow after them, ²⁴for as the lightning, when it flashes out of one part under the sky, shines to another part under the sky, so will the Son of Man be in his day.

²¹Then if anyone tells you, ‘Look, here is the Christ!’ or, ‘Look, there!’ don’t believe it.

¹If a prophet or a dreamer of dreams arises among you, and he gives you a sign or a wonder, ²and the sign or the wonder comes to pass, of which he spoke to you, saying, “Let’s go after other gods” (which you have not known) “and let’s serve them,” ³you shall not listen to the words of that prophet, or to that dreamer of dreams; for the LORD your God is testing you, to know whether you love the LORD your God with all your heart and with all your soul.

⁴³I have come in my Father’s name, and you don’t receive me. If another comes in his own name, you will receive him.
