Purification from what? Apparently giving birth, even to the Messiah, according to Biblical references makes a woman unclean and she has to go through the proper purification rituals before she's fit company again.
She was only restricted from a few very specific things.
Le:12:4:
And she shall then continue in the blood of her purifying three and thirty days;
she shall touch no hallowed thing,
nor come into the sanctuary,
until the days of her purifying be fulfilled.
Hasn't it struck you on reading his many epistles that Paul apparently hated and feared women? A certain amount of that's hardly a surprise in a pre-scientific and largely pre-literate culture full of superstition. People who routinely bleed for several days every month without any obvious debilitating effects must have seemed pretty mysterious. Can't you imagine the thought pattern? A man who bled from anywhere for several days would probably die, all women of a certain age do it routinely, from their most intimate orifice, they must have some mysterious power, better take control of that and put it down pretty quickly... Echoes of that attitude still linger in our own culture. But Paul goes way over the top.
I wouldn't go so far as putting Paul in that boat, I can find texts where he is harsh to the way men can and did act. Back in those days women were sub-servant to men. Men were the ones who brought home the paychecks, held most, if not all positions of any importance.
Really, woman have been having periods since they were able to conceive, it was maybe a mystery of why but certainly no big surprise that they would have them.
That's not what I said. The anti-Semitism's in the New Testament. Jews are repeatedly portrayed as the killers of the Messiah--somehow they lose sight of the fact that if Christ hadn't died as he did none of this would have worked--, Paul complains repeatedly about them abusing him, and Peter and John offer many other complaints against them.
My mistake. True Jesus's death was part of prophecy, and so were many things that lead upto that. Does that excuse them from the deaths of others who God sent to them, OT prophets, Stephen and the persecution of Christian around the same time? I don't think it does. I doubt God saw Christ's death as an abomination, Stephen would have been a whole other matter.
The rivers in the verse below are the nation of Israel when their eyes are opened, and the fish are the people of all nations and shall be healed.
Eze 47:9 And it shall come to pass, that every thing that liveth, which moveth, whithersoever the rivers shall come, shall live: and there shall be a very great multitude of fish, because these waters shall come thither: for they shall be healed; and every thing shall live whither the river cometh.
That chapter makes just as much sense if taken in a strictly literal sense, maybe even more so because it has a plain meaning with no mental picture switching.
It starts out at the temple Christ himself will build. It then goes on to give some indication of how big this river is, about 6,000 ft is as far as the dimensions go. Assuming the other side is similar you now have 12,000ft plus whatever distance that where swimming would be required. The banks are lined by trees on both sides (remember this part because I will get back to those trees). if you head east from where Jerusalem is now you end up at the dead sea, those are the waters that are healed. The valley the river flows through (to a sea to the east and to the west) is created when this verse occurs,
Zec:14:4:
And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east,
and the mount of Olives shall cleave in the midst thereof toward the east and toward the west,
and there shall be a very great valley;
and half of the mountain shall remove toward the north,
and half of it toward the south.
En-gedi is at the Dead Sea if this map is correct.

A literal view would also be understandable in that the marshes remain salty.
Eze:47:11:
But the miry places thereof and the marishes thereof shall not be healed;
they shall be given to salt.
Now back to the trees.
Eze:47:12:
And by the river upon the bank thereof,
on this side and on that side,
shall grow all trees for meat,
whose leaf shall not fade,
neither shall the fruit thereof be consumed:
it shall bring forth new fruit according to his months,
because their waters they issued out of the sanctuary:
and the fruit thereof shall be for meat,
and the leaf thereof for medicine.
You are entirely correct that all of Jacob's house and all of Israel's house will be healed, but that is in another section of Scripture.
These few verse do not give the whole picture.
Jer:31:8:
Behold,
I will bring them from the north country,
and gather them from the coasts of the earth,
and with them the blind and the lame,
the woman with child and her that travaileth with child together:
a great company shall return thither.
Jer:31:9:
They shall come with weeping,
and with supplications will I lead them:
I will cause them to walk by the rivers of waters in a straight way, wherein they shall not stumble:
for I am a father to Israel,
and Ephraim is my firstborn.
Words in the bible are meant to mean other than what the word means, so a study of them is necessary to extract the true picture of those verses.
Not always, just as written should always be the first option.
So healing is in order for them at the appointed time, for death spiritually will be no more as their eyes will be opened.
I'm pretty sure being resurrected will be quite an eye-opener for them, their joy will be in that everybody will be there, even the ones who plotted to kill Jesus.
So, you see, I have no urgency to convert anyone to Christianity, but will lead them there if they so desire.
You are right, Christ will gather whom He will when He will, some just get gathered before others. The second birth is baptism with God's Holy Spirit, you can't be condemned to the second death (fiery lake) if you have only had the 1st birth and that includes everybody alive today (and most who have long since gone to sleep, I would exempt those in Scripture who were Prophets and Apostles or others who were anointed by God) regardless if some claim to be 'born-again' these days because none of them can do any of the signs following that is a sign to others that a person does have the Spirit of God in them (2nd birth).
