Isn't that a reference to short-term events prophesied that fail to come to pass.It's right there in the middle of the oldest book in the Bible...
Deu 18:20-22
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. And if thou say in thine heart, How shall we know the word which the LORD hath not spoken? 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.
A prophecy for something far off in the future shouldn't be discounted. Example:
Acts 2:16-21 NIV
No, this is what was spoken by the prophet Joel:
17 “‘In the last days, God says,
I will pour out my Spirit on all people.
Your sons and daughters will prophesy,
your young men will see visions,
your old men will dream dreams.
18 Even on my servants, both men and women,
I will pour out my Spirit in those days,
and they will prophesy.
19 I will show wonders in the heavens above
and signs on the earth below,
blood and fire and billows of smoke.
20 The sun will be turned to darkness
and the moon to blood
before the coming of the great and glorious day of the Lord.
21 And everyone who calls
on the name of the Lord will be saved.’[a]
--- COMPARE ---
Joel 2:28-32 NIV
“And afterward,
I will pour out my Spirit on all people.
Your sons and daughters will prophesy,
your old men will dream dreams,
your young men will see visions.
29 Even on my servants, both men and women,
I will pour out my Spirit in those days.
30 I will show wonders in the heavens
and on the earth,
blood and fire and billows of smoke.
31 The sun will be turned to darkness
and the moon to blood
before the coming of the great and dreadful day of the Lord.
32 And everyone who calls
on the name of the Lord will be saved;
for on Mount Zion and in Jerusalem
there will be deliverance,
as the Lord has said,
even among the survivors
whom the Lord calls.[a]
