It says two parts will die, but in the all the land:

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.

This refers to, "in the land of Israel"?

Does this mean only the descendants of Jacob will die?

Or does the "two parts" also include the Palestinians?

Also, does the "two parts" NOT include those that are hidden in the wilderness for 1260 days?

Also, does the "two parts" NOT include the remnant of Israel, outside the land, still around the world?
