'Therein' in the Bible

Publish ye in the palaces at Ashdod, and in the palaces in the land of Egypt, and say, Assemble yourselves upon the mountains of Samaria, and behold what great tumults are therein, and what oppressions in the midst thereof.

The Lord GOD hath sworn by himself, saith the LORD the God of hosts, I abhor the excellency of Jacob, and hate his palaces: therefore will I deliver up the city with all that is therein.

Shall not the land tremble for this, and every one mourn that dwelleth therein? and it shall rise up wholly as a flood; and it shall be cast out and drowned, as by the flood of Egypt.

And the Lord GOD of hosts is he that toucheth the land, and it shall melt, and all that dwell therein shall mourn: and it shall rise up wholly like a flood; and shall be drowned, as by the flood of Egypt.
