John Trapp on Isaiah 8:21

Ver. 21. And they ſhall paſs through it] to and again as uncertain of their way: and even at their wits end.

When they ſhall be hungry] cum eſurierit & efferbuerit, as a Pot boyling caſteth up ſcum.

And curſe their King] Ahaz, ſay ſome; Zedekiah, ſay others.

And their God] As thoſe Antichriſtians, Rev. 16.10. The Chinois whip their Gods, when they pleaſe them not.

And look upward] as the hungerbit-Wolf howls againſt Heaven.
