'Sink' in the Bible

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.

For the Lord, Jehovah of hosts, is he that toucheth the land and it melteth, and all that dwell therein shall mourn; and it shall rise up wholly like the River, and shall sink again, like the River of Egypt;
