The difference is , a prediction can fail (like weather predictions every day!!!!!!!!)
Yahweh's Word NEVER FAILS.
Jeff,
A biblical prophecy/prediction can NEVER FAIL when the prophet receives it from God.
Human weather predictions (no matter how fancy the instruments used) provide a poor analogy to God's prophecies/predictions that will never fail, e.g. Micah 5:2.
It was prophesied in
Jeremiah 25:11-12 (NIV) that Judah would be ruled by Babylon for 70 years. The prophecy was given ca. 626-586 BC and was fulfilled 50 years later.
Isaiah 45:1 (NIV) was written ca. 701-681 BC. Babylon's gates opened for Cyrus is ca. 539 BC, thus fulfilling the prophecy 150 years later.
Nahum 3:15 (NIV) was prophesied ca. 614 BC,
'There the fire will consume you;
the sword will cut you down –
and it will devour you like a swarm of locusts.
Multiply like grasshoppers,
multiply like locusts!'
God, through Naham the prophet, predicted that Ninevah woud be destroyed by fire. Encyclopaedia Britannica reported that archaeologists found layers of ash on the ruins of that city:
Nineveh suffered a defeat from which it never recovered. Extensive traces of ash, representing the sack of the city by Babylonians, Scythians, and Medes in 612 BC, have been found in many parts of the Acropolis. After 612 BC the city ceased to be important (Encyclopaedia Britannica 2018. s.v. Ninevah).
There are many other OT prophecies that were fulfilled in the OT era.
