Bible Notes Online - Isaiah 23 - ESV
Commentary

v1-3: Tyre, the city of trade, a busy seaport, a market place for the nations, enjoying widespread influence through its trade. Tyre and Sidon had strong links with Egypt, the harvest of the Nile being their revenue. When Sidon is judged, Egypt responds in sorrow (v5).

v4-5: Shame and disappointment for those who put their trust in Tyre. It was almost that they worshipped the sea that brought its wealth.

v6-7: Wail for the city, no longer the joyous city.

v8-9: The greatness of Tyre; a long history, widely respected, whom none had challenged. Proud Tyre, a self-made city-state; yet this great city was to be brought low by the Lord God, before whom none can stand.

v10-14: The lament for Tyre, as he looked for comfort from other nations, but found none. Assyria was the nation to defeat Tyre and Sidon, as well as Babylon.

v15-18: See Ezelk27-28; Rev 17.1-2; like Babylon, Tyre had a worldwide evil influence, but there was a sudden decisive judgment from God. Later her influence would recommence, but her gain will be for the Lord and for His people, as the kings of the earth bring their glory to God.
