Deuteronomy 18:22

22 When a prophet makes a statement in the name of the Lord, if what he says does not take place and his words do not come true, then his word is not the word of the Lord: the words of the prophet were said in the pride of his heart, and you are to have no fear of him.

Deuteronomy 18:22 Meaning and Commentary

Deuteronomy 18:22

When a prophet speaketh in the name of the Lord
Says he comes from God, is sent by him, and has a commission from him to say so:

if the thing follow not, nor come to pass;
as the prophecy of Hananiah, ( Jeremiah 28:3 ) that is the thing which the Lord hath not spoken; or otherwise it would have come to pass, unless when a condition is either expressed or implied, as the repentance or disobedience of a people; see ( Jeremiah 18:7-10 )

but the prophet hath spoken it presumptuously;
in a bold and daring manner, with great impiety and impudence, out of his own head and heart, being a mere device and imagination of his own, which, not having the fear of God, he delivered as coming from the Lord:

thou shall not be afraid of him;
not only to reprove him for his wickedness, but also to punish him for it; showing no regard to the high character he assumes, nor to the great pretensions he makes to sanctity, knowledge, and familiarity with God.

Deuteronomy 18:22 In-Context

20 But the prophet who takes it on himself to say words in my name which I have not given him orders to say, or who says anything in the name of other gods, will come to his death.

21 And if you say in your hearts, How are we to be certain that the word does not come from the Lord?

22 When a prophet makes a statement in the name of the Lord, if what he says does not take place and his words do not come true, then his word is not the word of the Lord: the words of the prophet were said in the pride of his heart, and you are to have no fear of him.
