I have shown it before, the elect in Matt. 24 are Israel. The entire 24th chapter of Matt. is addressed to the Jews.
Isa. 11:11-12
"And it shall come to pass in that day, that the Lord shall set his hand again the second time to recover the remnant of his people, which shall be left, from Assyria, and from Egypt, and from Pathros, and from Cush, and from Elam, and from Shinar, and from Hamath, and from the islands of the sea.
And he shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth."
This is the gathering of Matt. 24:31. It is Israel!
