Are Jews still God's Chosen People ?
Do you mean more special than any of the other children of Adam and Eve?
Ge:3:15 is quite an important verse. Jesus was the 'seed of Eve', the group Mary belonged to started with Abraham's son. From Adam to Abraham is where the OT Saints that are resurrected with Jesus come from. They ascended to the Re:4 Temple and are serving as the 24 Elders in Re:5. Re:12 is an expansion on that verse. Eve is the 1st woman, Mary the mother of Jesus is the 2nd woman, Mary of Bethany represents the last woman based on believers being 'her Christian followers'.
The 12 stars represent 12 OT Saints from that earliest time. They are in the same form Jesus was when He asked Mary M. not to touch Him. They will get a glorified body when they and all the people Re:20:4 represents visit the Eze:47 tree of life scene. They will pass on what they are now learning so that the group will not be sent to the fiery lake with sinful immortals.
12 stars become 24 people because the wives of those 12 men will be with them, in an unmarried condition, so they do not have any children. That is for the flock in Isa:65 when they make their homes outside of New Jerusalem.
Ever read the parable of 'the penny'. The group gathered at the end would seem to who 'God's people are:
M't:20:1-2:
For the kingdom of heaven is like unto a man that is an householder,
which went out early in the morning to hire labourers into his vineyard.
And when he had agreed with the labourers for a penny a day,
he sent them into his vineyard.
.
.
M't:20:9-15:
And when they came that were hired about the eleventh hour,
they received every man a penny.
But when the first came,
they supposed that they should have received more;
and they likewise received every man a penny.
And when they had received it,
they murmured against the goodman of the house,
Saying,
These last have wrought but one hour,
and thou hast made them equal unto us,
which have borne the burden and heat of the day.
But he answered one of them,
and said,
Friend,
I do thee no wrong:
didst not thou agree with me for a penny?
Take that thine is,
and go thy way:
I will give unto this last,
even as unto thee.
Is it not lawful for me to do what I will with mine own?
Is thine eye evil,
because I am good?
That could apply to Zec:14 as the Gentile Church is alive at the same time the !2 Tribes are. The 12 Tribes are whole, while the Church is a small segment of 'all Gentiles'. The Re:20:4 group could say that about the Re:20:5 group except in the new earth era they are the flock the shepherds in order for the shepherds to grow in wisdom, while the flock grows in numbers as well as wisdom that gets passed down to them from the people who will call new Jerusalem home.
