Ezekiel 34:
23. And I will set up one shepherd over them, and he shall feed them, even my servant David; he shall feed them, and he shall be their shepherd.
24. And I the LORD will be their God, and my servant David a prince among them; I the LORD have spoken it.
25. And I will make with them a covenant of peace, and will cause the evil beasts to cease out of the land: and they shall dwell safely in the wilderness, and sleep in the woods.
Ezekiel 37:
21. And say unto them, Thus saith the Lord GOD; Behold, I will take the children of Israel from among the heathen, whither they be gone, and will gather them on every side, and bring them into their own land:
22. And I will make them one nation in the land upon the mountains of Israel; and one king shall be king to them all: and they shall be no more two nations, neither shall they be divided into two kingdoms any more at all.
23. Neither shall they defile themselves any more with their idols, nor with their detestable things, nor with any of their transgressions: but I will save them out of all their dwelling places,
wherein they have sinned, and will cleanse them: so shall they be my people, and I will be their God.
24. And David my servant shall be king over them; and they all shall have one shepherd: they shall also walk in my judgments, and observe my statutes, and do them.
25. And they shall dwell in the land that I have given unto Jacob my servant, wherein your fathers have dwelt; and they shall dwell therein, even they, and their children, and their children's children for ever: and my servant David shall be their prince for ever.
26. Moreover I will make a covenant of peace with them; it shall be an everlasting covenant with them: and I will place them, and multiply them, and will set my sanctuary in the midst of them for evermore.
27. My tabernacle also shall be with them: yea, I will be their God, and they shall be my people.
28. And the heathen shall know that I the LORD do sanctify Israel, when my sanctuary shall be in the midst of them for evermore.
John 10:
14. I am the good shepherd, and know my sheep, and am known of mine.
15. As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep.
16. And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
When will He gather said other sheep out of those Israelites scattered among the heathen?
The first part - Matthew 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:
6. But go rather to the lost sheep of the house of Israel.
7. And as ye go, preach, saying, The kingdom of heaven is at hand.
8. Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give.
16. Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves.
17. But beware of men: for they will deliver you up to the councils, and they will scourge you in their synagogues;
18. And ye shall be brought before governors and kings for my sake, for a testimony against them and the Gentiles.
19. But when they deliver you up, take no thought how or what ye shall speak: for it shall be
given you in that same hour what ye shall speak.
20. For it is not ye that speak, but the Spirit of your Father which speaketh in you.
21. And the brother shall deliver up the brother to death, and the father the child: and the children shall rise up against their parents, and cause them to be put to death.
22. And ye shall be hated of all men for my name's sake: but he that endureth to the end shall be saved.
23. But when they persecute you in this city, flee ye into another: for verily I say unto you, Ye shall not have gone over the cities of Israel, till the Son of man be come.
So much for notions of 70AD, and books about Peter in Rome and James in India, and more, and more "books about."
Matthew 24:
29. Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
30. And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power
and great glory.
31. And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
So what happened?
