By this name he had made himself known in delivering them out of Egypt, Exod. vi. 3. God will do something to vindicate his own honour, something for his great name; and his people, who have almost lost the knowledge of it, shall know it to their comfort and shall find it their strong tower. They shall know that God's providence governs the world, and all the affairs of it, it is he who speaks deliverance for them by the word of his power, that it is he only, who at first spoke and it was done. They shall know that God's word, which Israel is blessed with above other nations, shall without fail have its accomplishment in due season, that it is he who speaks by the prophet; it is he, and they do not speak of themselves; for not one iota or tittle of what they say shall fall to the ground.
