Deuteronomy 18:21-22

Deuteronomy 18:21-22

[21] And if thou say  in thine heart,  How shall we know  the word  which the LORD  hath not spoken?  [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.
