1) Israel will prevail over its enemies (Isaiah 41:12-14..written 701-681 BC)
The verse says that "the men at war with you will become as something nonexistent, as nothing at all." This clearly was NOT fulfilled. Rather, Israel had become "something nonexistent" for centuries, and now it exists again but there are still many nations 'at war with them' that DO exist.
2)The ruins of Israel would be rebuilt. (Amos 9:11,13....written 750 BC)
Well, yes, this was to expect. Why should the land be devastated forever? It was obvious that at some time someone would build something there.
3) Ezekiel prophesied for morden day Israel (Ezekiel 36:11..written 593-571 BC).
Really? "Yes, I will multiply your people and your livestock; they will increase and be fruitful. And I will cause you to be inhabited as you were formerly, and I will make you prosper more than in the past"
The prophecy just says that Israel would "be inhabited." But ... if you believe in the Bible account of Solomon, that he was by far the greatest and richest king of all times of all the earth, does modern Israel really "prosper more than in the past?"
4)Tress again would grow in Isreal. (Isaiah 41:18-20...written 593-571 BC)
Ha! No one could foresee that in a land with water, trees would grow. Really. Only God could see that. ;)
5)Israel's fruit would fill thw world. (Isaiah 27:6...written 701-681 BC)
Does it? The verse actually says that their fruit would fill "the land," not "the world." Well, another thing that is not too hard to prophesy. Of course, Israel's fruit would fill Israel. Why should Germany's fruit fill Israel?
6)Jerusalem would become the world's most inportant religious site. (Micah 4:! written 750-686 BC)
The verse refers to the 'mountain of the house of JHWH', and it says that this house would be firmly established and stream there.
Obviously, there is no "house of JHWH" there today, so this is another unfulfilled prophecy.
7)Egypt would never again rule over other nations. (Ezekiel 29:15..written 593-571)
Well, they never gained their previous power. But verse 14 actually said that "they will become an insignificant kingdom," and this did not really apply during the Greek/Macedonian rule.
8) Zechariah 8: 7-8, Jews return to Jerusalem (written 520-518 BC)
Besides that this was also not too hard to prophesy, most scholars consider the prophecy written in the 4th or 3rd century BC.
