Verse 9 asks two questions that are both answered with a "No". Yahweh will NOT shut the womb as the children are in the process of being "brought forth" (born).
You do see how He says they are born in one day don't you? Caught up in the clouds in the rapture. They will be caught up and the devil will be throne down to earth for the next 3-1/2yrs and those who were not ready to make holiness as his body when he came, will have to die as martyrs just as all those,they will not make heaven.
Rev 14:12
Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
13 And I heard a voice from heaven saying unto me, Write, Blessed are the dead which die in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.
14 And I looked, and
behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle.
15 And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe.
KJV
I do not believe that once the rapture happens, that there will be new believers to become saved. The saints in 14:12 will have been those who had received Christ before the time was up and will have a chance to be martyred, but no new members once the WRATH of God begins.
Rev 11:14 The
second woe is past; and, behold, the third woe cometh quickly.
15 And
the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
16 And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,
17 Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned.
18 And
the nations were angry, and thy wrath is come, and the time of the dead(spiritually dead but on earth), that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
19 And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an
earthquake, and great hail.
Revelation 12
12:1 And there appeared a great wonder in heaven;
a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars:
2 And she being with child cried, travailing in birth, and
pained to be delivered.
3 And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.
4 And his tail drew the third part of the stars of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered,
for to devour her child as soon as it was born.
5 And
she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne.
6 And
the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days.
7 And
there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
8 And prevailed not; neither was their place found any more in heaven.
9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
