Isaiah 23:10-13. “Pass through thy land as a river, O daughter of Tarshish: there is no more strength. He stretched out His hand over the sea, He shook the kingdoms: the Lord hath given a commandment against the merchant city, to destroy the strong holds thereof. And He said, Thou shalt no more rejoice, O thou oppressed virgin, daughter of Zidon: arise, pass over to Chittim; there also shall thou have no rest. Behold the land of the Chaldeans; this people was not, till the Assyrians founded it for them that dwell in the wilderness: they set up the towers thereof, they raised up the palaces thereof; and He brought it to ruin.
Remember that Babylon is the same as Chaldea. This map helped put things into perspective for me. The reach of Assyria was amazing, really, for the time in which it dominated the vast area that it did.
In verse 10, Tarshish is set free. Just as the Nile overflows its banks, so the people can now enjoy liberty and be independent of the mother city. It can exercise no more restraining girdle of authority. Let the Zidonians escape to Cyprus (Chittim); they will have no rest there. The Chaldeans, who succeeded the Assyrians (v. 13), would desolate Tyre and bring it to ruin (Ezek. 29:17, 18). During the seventy years of Chaldean rule (Jer. 25: 9, 11; 29:10) Tyre would be forgotten.
