The last division of the Book contains the prophet's announcement of the coming of Messiah. It falls into three sections, one dealing with the coming One, one dealing with the Coming Day, and one uttering the closing words.
The prophet announced the advent of Jehovah's Messenger, describing His Person and the process of His administration, and finally declaring the principle of the unchangeableness of Jehovah.
He next appealed to the nation generally, calling the people, to return, and then making a twofold charge against them of robbery and of blasphemy. To each of these they responded kith the same inquiry, "Wherein?" and thus showed that like the priests, they were observing formalities of religion while being deficient in true spiritual life.
In all this widespread apostasy a remnant still remained loyal to Jehovah, whom the prophet described, and then addressed, declaring to them Jehovah's knowledge of them and determination concerning them.
