Using wicked tyrants to chastise the sins of His church.

[EvanVK]

“This verse contains two clauses. First, he declares that God will punish a wicked king. Secondly, he suggests that the time is not yet come, in order to encourage believers to the exercise of patience. He foretells that the time which God regards as fit for doing it will be, when he shall have chastised the sins of his Church; in the same manner as if the master of a house were to settle the disturbances of his own family. The object which he has in view is, that believers may not give way to despondency, when they behold a wicked tyrant in such a state of exultation, and may not abandon the hope of salvation, as if it were impossible to restrain him.” Calvin’s comments on Isaiah 10:12
