Ethnic cleansing is directed at 'ETHNICITY'
God's Judgment is directed at SIN.
Go back and READ CAREFULLY
God does both.
He commanded Joshua to enter Canaan with the Ark before then and utterly destroy every man, woman, and child, infant, and baby in the womb, all the cattle, livestock, and destroy everything.
God destroyed the sin and the people committing the sin.
He will do the same thing at the last judgment.
20 So the people shouted when the priests blew with the trumpets: and it came to pass, when the people heard the sound of the trumpet, and the people shouted with a great shout, that the wall fell down flat, so that the people went up into the city, every man straight before him, and they took the city.
21
And they utterly destroyed all that was in the city, both man and woman, young and old, and ox, and sheep, and ***, with the edge of the sword.
Joshua 6:19–21.
In order to understand the end, one must go to the beginning. The Tree of Life was kept from Adam and the woman, but in Revelation the Tree of Life is given to God's covenant people.
In order to understand Zechariah 14:21 one must go to Genesis 12:6.
The land God promised Abraham was occupied by what is called the Canaanite. This is a general term for those who lived in Canaan. And there were many nomadic tribes that occupied the land. All you need to do is read Joshua to see the individual tribes that lived there that God commanded the children of Israel to destroy.
6 And Abram passed through the land unto the place of Sichem, unto the plain of Moreh. And
the Canaanite was then in the land. Gen. 12:6.
When God sits on His throne in Jerusalem, He gives the land He promised to Abraham and his seed. God personally cleanses the land of all Gentiles. The Canaanite represents the non-Hebrew Gentiles just as the Canaanite in Genesis represented the non-Hebrew Gentiles. And they were not at all considered "Gentile" until the covenant with Abraham was made and God placed a distinct separation between both groups of peoples through the rite of circumcision and by virtue of the covenant promises. Now, in all the earth there were those in covenant with God (Abraham and his seed) and those NOT in covenant with God (those NOT Abraham's seed -Gentiles/Canaanites.)
21 Yea, every pot in Jerusalem and in Judah shall be holiness unto the LORD of hosts:
And all they that sacrifice shall come and take of them, and seethe therein:
And in that day there shall be no more the Canaanite in the house of the LORD of hosts.
Zech. 14:21.
NO MORE GENTILES (non-Hebrew, non-covenant, uncircumcised) will ever occupy the Promised Land ever again.
And on that day the House of the Lord will be ONE House. The King of the Jews will unify both Houses into one House and it will be called the House of the Lord. Not the House of Israel, or the House of Judah, but the House OF THE LORD.
Aren't you happy for the Jews?
