What does Zechariah 13:8 predict will happen to Israel?

Zechariah 13:8 predicts that in all the land of Israel, two parts—two thirds—will be cut off and die, but the third part will be left therein and survive. This contrasts with the teaching that all Israel will be saved.

Les explains that Zechariah 13:8 is set in the land of Israel and says two parts—two thirds—will be cut off and die, while the third part will be left and survive. Verse 9 then says God will bring that third part through the fire. Les teaches that fire in this text depicts testing, like purifying gold by heat, and that God will bring this third part of Israel through the testings of the tribulation, refining them as silver is refined and trying them as gold is tried. This qualifies the claim that all Israel shall be saved in Romans 11.

Zechariah 13:8

And it shall come to pass, that in all the land, saith the LORD, two parts therein shall be cut off and die; but the third shall be left therein.

In Zechariah 13:8, what happens to two-thirds of Israel?

Zechariah 13:8 states that in all the land of Israel, two parts—two-thirds—shall be cut off and die. Only the third part shall be left therein and survive. This contrasts with the claim that every Jew will be saved, because the verse says two-thirds are cut off and die.
