'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;

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

And every pot in Jerusalem and in Judah shall be holiness unto Jehovah 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 a Canaanite in the house of Jehovah of hosts.
