I don't know if it's appropriate to debate the scripture in this thread or not since the OP was just asking for other people's input on Matt 25:1-13. Let me know if it's not appropriate to debate it here and, if it's not, I'll just delete this post.
But, it's hard for me to read something like this and not respond. You're indicating that you think the virgin group that doesn't go up to be with Christ represents non-believing Israel and they would be left to become tribulation saints. I don't know how that can be possible in light of what it says at the end of the parable.
Matt 25:10 “But while they were on their way to buy the oil, the bridegroom arrived. The virgins who were ready went in with him to the wedding banquet. And the door was shut. 11 “Later the others also came. ‘Lord, Lord,’ they said, ‘open the door for us!’ 12 “But he replied, ‘Truly I tell you, I don’t know you.’ 13 “Therefore keep watch, because you do not know the day or the hour.
First of all, why would it matter if they missed the wedding if they would still get a chance to be saved after being shut out of it? Why the warning to "keep watch" if they would get a second chance to be saved after that, anyway? What difference does it really make if they're saved before or after the wedding in that case?
Notice that the Bridegroom in this parable, representing Jesus, says to the foolish virgins: "Truly I tell you, I don't know you".
Matthew 7:21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven. 22 Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles?’ 23 Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’
Clearly, Jesus is not happy at all with people who pretend to be Christians and even do some good things, but don't have a personal relationship with Him. They will try to plead their case, but He will just say "I never knew you. Away from me, you evildoers!". That doesn't sound like something He would say to people who He's giving another chance to be saved.
When else would they be trying to plead their case except on judgment day when everyone has to give an account of themselves? If you continue reading in Matthew 25 in verses 31-46, you can see that when Jesus comes with His angels there won't be a time of tribulation following that. Instead, He will sit on the throne of His glory to judge all people. That will be the time when people try to plead their case that they did all these things like prophesy in His name and perform miracles, but He will say He never knew them and will say to them "Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels" (Matt 25:41).
Another way to show that there is no tribulation period after what is described in Matthew 25:1-13 is the fact that His coming of which no one knows the day or hour is also described in Matthew 24:29-36 and it is said to occur after the tribulation of those days.
So, with all that in mind, I believe Jesus is contrasting believers and unbelievers (not just unbelieving Israelites) in general in Matthew 25:1-13 and what will happen to each on the day He returns. Later in the chapter He gets more specific about what happens to each group (see Matt 25:34, 41 and 46).
