Deuteronomy 18:20-22 NASB - 20 'But the prophet who speaks a word presumptuously in My name which I have not commanded him to speak, or which he speaks in the name of other gods, that prophet shall die.' 21 "You may say in your heart, 'How will we know the word which the LORD has not spoken?' 22 "When a prophet speaks in the name of the LORD, if the thing does not come about or come true, that is the thing which the LORD has not spoken. The prophet has spoken it presumptuously; you shall not be afraid of him.
Shalom.

[Deu 13:1-5
1 "If there arises among you a prophet or a dreamer of dreams, and he gives you a sign or a wonder,
2 "and the sign or the wonder comes to pass, of which he spoke to you, saying, 'Let us go after other gods'--which you have not known--'and let us serve them,'
3 "you shall not listen to the words of that prophet or 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.
4 "You shall walk after the LORD your God and fear Him, and keep His commandments and obey His voice; you shall serve Him and hold fast to Him. 5 "But that prophet or that dreamer of dreams shall be put to death, because he has spoken in order to turn [you] away from the LORD your God, who brought you out of the land of Egypt and redeemed you from the house of bondage, to entice you from the way in which the LORD your God commanded you to walk. So you shall put away the evil from your midst.
[Jhn 6:29
29 Jesus answered and said to them, "This is the work of God, that you believe in Him whom He sent."
[2Jo 1:7-11
7 For many deceivers have gone out into the world who do not confess Jesus Christ [as] coming in the flesh. This is a deceiver and an antichrist.
8 Look to yourselves, that we do not lose those things we worked for, but [that] we may receive a full reward.
9 Whoever transgresses and does not abide in the doctrine of Christ does not have God. He who abides in the doctrine of Christ has both the Father and the Son.
10 If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him;
11 for he who greets him shares in his evil deeds.
