John Wesley on Isaiah 5:26

An ensign - To call them together for his service. From far - To the Chaldeans; for even Babylon is called a far country, chap.39:3. And he saith nations, because the Chaldean army was made up of several nations. Will hiss - Or, will whistle unto, or for them: will gather them together by his word. as shepherds gather their sheep. He intimates how easily and speedily God can do this work. From the ends - Which is not to be understood strictly, but with a latitude, from very remote places.
