Charles Ellicott Commentary Isaiah 23:5

"When the report cometh to Egypt, they shall be sorely pained at the report of Tyre." — Isaiah 23:5 (ASV)

As at the report concerning Egypt ... —Better, When the report comes to Egypt ... The news of the capture of Tyre would cause dismay in Egypt, partly because the export trade of their corn depended upon it, partly because it had served as a kind of outpost against the Assyrians, who, under Sargon (Records of the Past, vii. 34) and Sennacherib (2 Kings 18:21; 2 Kings 19:8), were pressing on against the Ethiopian dynasty then dominant in Egypt.
