I don't see how you get this from that passage. The closest I see any reference that can be interpreted as the Jews is "brethren". However, I think in this case it is more aptly understood as Christians.
Because it is coming after Christ's return.
This is dealing with those who survived the Tribulation, which the Church doesn't go through.
Although I am on the same page as some of my brothers in Christ here, I am of that small group who believes in different ways of salvation for the people of different dispensations...
The difference between me and the A and Post Millennialists is that I won't jump up and down and scream at those who disagree with me...:)
As you know, Jesus came to minister to the Jews...
Mat 15:24 But he answered and said, I am not sent but unto the lost sheep of the house of Israel.
And Jesus even told his Apostles to stay away from the Gentiles...
Mat 10:5 These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not:
Mat 10:6 But go rather to the lost sheep of the house of Israel.
Mat 10:7 And as ye go, preach, saying, The kingdom of heaven is at hand.
The Kingom of Heaven...Jesus was ready to take up his position of King of King and Lord of Lords and take up His rightful position of the Throne right there in Jerusalem...
Gentiles were not invited...It would have been a Jewish church in a Jewish Kingdom...
Matthew chapter 5, the Beatitudes are directed at the Jews in the Kindom of Heaven, the physical Kingdom of The King on the Throne in Jerusalem...
Mat 5:10 Blessed are they which are persecuted for righteousness' sake: for theirs is the kingdom of heaven.
And as you read chapter 5, and much of the Gospels, you'll see a large elements of works combined with faith are necessary to gain salvation...
But the Jews rejected their Messiah...
And the Gentile church was born...
But when the Jews (and anyone) during the Tribulation pick up the Bible, they go to Matthew and the other Gospels and Hebrews and James and I and II Peter, etc., to get their directions from God...
I realize most will disagree with me but I'm fine with that...
