Verse 13
Ephraim, as I saw Tyrus - Tyre was strongly situated on a rock in the sea; Samaria was on a mountain, both strong and pleasant. But the strength and beauty of those cities shall not save them from destruction.
Ephraim shall bring forth his children to the murderer - The people shall be destroyed, or led into captivity by the Assyrians. Of the grandeur, wealth, power, etc., of Tyre, see the notes on Ezekiel 27 (note) and Ezekiel 28 (note).
