In reply to your 11/14 post What does the two parts include? (fivedoves.com) the following verse refers to 2/3's of the people in all the land being cut off and dying leaving 1/3 of the people in the land of Israel.

Zech. 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."

(I don't know the answers to the rest of your questions in your above post.)
