According to Deuteronomy 18:20-22, it only takes one false prophecy to make a prophet false, just as it only takes one murder to make a person a murderer
Deu 18:20 But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.
Deu 18:21 And if thou say in thine heart, How shall we know the word which the LORD hath not spoken?
Deu 18:22 When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that [is] the thing which the LORD hath not spoken, [but] the prophet hath spoken it presumptuously: thou shalt not be afraid of him. Deuteronomy 18:20-22
