Isaiah 66:6 - Wesley's Explanatory Notes

A voice — The expression of a prophetical extasy, as if he said, I hear a sad and affrighting noise; it comes not from the city only, but from the temple, wherein these formalists have so much gloried. There is a noise of soldiers slaying, and of the poor people shrieking or crying out. Of the Lord — A voice of the Lord, not in thunder, but that rendereth recompence to his enemies. Thus he seems to express the destruction of the Jews by the Roman armies, as a thing at that time doing.
