'Therein' in the Bible

And said unto him, Run, speak to this young man, saying, Jerusalem shall be inhabited as towns without walls for the multitude of men and cattle therein:

The black horses which are therein go forth into the north country; and the white go forth after them; and the grisled go forth toward the south country.

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.

And men shall dwell therein, and there shall be no more curse; but Jerusalem shall dwell safely.

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.
