“Wherefore it shall come to pass, that when the Lord hath performed his whole work upon mount Zion and on Jerusalem, I will punish the fruit of the stout heart of the king of Assyria, and the glory of his high looks.”
King James Version (KJV)
10:12 Wherefore - Because of this impudent blasphemy. His work - Of chastising his people so long as he sees fit. Looks - His insolent words and carriage.
