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 Jehovah hath sworn by himself, saith Jehovah, 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? yea, it shall rise up wholly like the River; and it shall be troubled and sink again, like the River of Egypt.
