But the LORD of hosts shall be exalted in judgment, and God that is holy shall be sanctified in righteousness.
But the Lord of hosts shall be exalted in judgment. God shall be "exalted" in man's view, because of His manifestation of His "justice" in punishing the guilty.
And God, that is holy, shall be sanctified in righteousness - shall be reverenced and worshipped as holy, by reason of His 'righteous' dealings.
