First off, you didn't tell me when the "mark of the beast" was enacted upon the earth so that no one was able to eat, buy or sell without the mark? When did that happen? And second, as far as the verses you cited, Well let's answer them one by one (taking into consideration their full context):
1.) exodus 11 - there never has again been such a great cry IN EGYPT, since all of Egypt's firstborn were killed. Do you know of a time when there was?
2.) Ezekiel 5 - if you look at the context (not just verse 9 plucked out in isolation) it is IMMEDIATELY followed by "THEREFORE father's shall eat their sons in your midst, and sons shall eat their fathers." I am not sure any other time when this cannibalism was true in Jerusalem, so it seems this is specifically what manner of judgement verse 9 is referring to.
3.) 2 Kings 18 - I think it means exactly what it says (seems people try to say often the Bible doesn't mean anything or doesn't mean what it says, Hebraic word phrases aside, sometimes to me to support their ism). ESV Study Bible commentary on that verse = " hezekiah's trust was unparalleled in Judean history, & was evidenced in the way he HELD FAST to God throughout his life, in contrast to Solomon, who in his old age "HELD FAST" to foreign wives and broke the Law of Moses."
4.) Joel 2:2 - I believe Joel 1 speaks of the current situation they were in at the time in Judah, but I, & many commentators & scholars alike, believe in chapter 2 Joel is speaking of a future judgement that will come - a mighty army set against Judah. This is made clearer in its full prophetic context by looking at the fact that in 2:1 just before that Joel says "for the day of the Lord is coming; it is near..." The Day of the Lord should be clear to us as to when it is referring, when Christ returns to judge the quick and the dead. So this judgement of this people the world never has or ever will see again, is in the context of (just prior to) the "Day of the Lord". 70 AD was a little "type" of this, but the actual & full/final fulfillment is still yet to come. And in classic prophetic, God-Style, the Assyrians are the ancient ancestors of the radical Islamicists of the 10/40 window. Those countries which now surround Israel & hate her (& the Christians) with an unnatural, satanicly inspired rage. The language the Assyrians spoke disappeared, but it's closest remaining language from its roots is Arabic. And who is more feared than the likes of ISIS & these types? None since the Asdyrians in all the earth. "TERRORism". There are a hundred other clear connections, including the Antichrist clear parallel fulfillment a of all the NT passages, etc.
5.) 2 Kings 23 - I think it means just what it says (why my 5th child's middle name is Josiah, which means "The Lord burns" or "Our God is an everlasting Fire"). ESV Commentary on verse 25 says, "In spite of several generations of idolatry and rebellion against the Lord, somehow Josiah arose as a righteous king who not only appeared outwardly to be righteous but turned to the Lord with all his heart and with all his soul and with all his might, according to all the Law of Moses. Me = Pretty self explanatory. I think God meant what is written there. Don't "absolutize" the phrase "never was not ever will be again" to equate exactly what qualities in Josiah the Lord was speaking to as EXACTLY the same as what the Lord spoke of Hezekiah's on in the other passage (though related, not exactly identical). Hezekiah's TRUST in God shines through & Josiah's ZEAL & OBEDENCE shine through (though both shared in all these traits for sure for the Lord to single them out & speak in such ways in holy writ).
6.) Daniel 9:12 - that's pretty simple. This is Daniel speaking and what was done at that time never had been done before in Israel? Not sure what is so mysterious to you at all on that one?
Again, although some of these texts require a closer look and study, some want to just pluck texts out of their context (which creates a "pretext" & eisegesis rather than exegesis) to support their own thinking/isms. Not saying at all you're doing this Todd, but I see it ALL the time. Especially since the Bible originally had not only no chapter numbers but no verse numbers. The addition of chapters, & verses, & the quick Google search has all in my opinion caused us to evaluate & compare scripture with scripture in an often isolated, eisegesis, incomprehensive, and wrong way.
FYI - ALL CAPS are not yelling but are for emphasis since Bold & italics are not possible in this format.
Anyways, good questions TMK.
God Bless,
