It is God who actually confounds the visions of false prophets like cult leaders.

24 Thus says the Lord, your Redeemer, and He Who formed you from the womb: I am the Lord, Who made all things, Who alone stretched out the heavens, Who spread out the earth by Myself [who was with Me]?—

25 [I am the Lord] Who frustrates the signs and confounds the omens [upon which the false prophets’ forecasts of the future are based] of the [boasting] liars and makes fools of diviners, Who turns the wise backward and makes their knowledge foolishness,

26 [The Lord] Who confirms the word of His servant and performs the counsel of His messengers, Who says of Jerusalem, She shall [again] be inhabited, and of the cities of Judah, They shall [again] be built, and I will raise up their ruins,

Isaiah 44:24-26
