Isaiah 66:5

(5) Hear the word of the Lord . . .—The prophet turns from the hypocrites to the persecuted remnant. The self-righteous, self-exalting Pharisee (comp. Isaiah 65:5) repudiates, and, as it were, excommunicates, the true worshippers, and taunts them with their devotion to a God who does not help them. In words which find an echo in Matthew 27:42, they said, “Let Jehovah glorify Himself, that we may look on your joy.” The prophet adds the doom that shall fall upon the mockers: “They, and not those whom they deride, shall be put to shame.”
