1 John 4:1
Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many
false prophets have gone out into the world.
2 Peter 2:1
But false prophets also arose among the people, just as there will be false teachers among you,
who will secretly bring in destructive heresies, even denying the Master who bought them,
bringing upon themselves swift destruction.
